Flight Simulator 2020 Does Caching Work at all??? In this video I talk about some extensive testing that I did on the 2 caching systems in FS2020. The answer to this question is not a simple yes or no!
All of the footage in this video of flying around the Hollywood Ca. area was with manual caching at the low quality setting.
Here is a list of all of the locations in the sim that were created with photogrammetry. Make sure you manually cache any of these locations if you want to visit them with the highest visual fidelity:

What a voice. This man was born to speak into a microphone.
Awww you're too kind :)
I think he should start a voice over career its worth a shot. Can see him featuring in documentaries. Such a soothing voice it’s so settling.
@@OzzySafa Thanks!
As an audio professional I wholeheartedly agree. Top notch!
@@Cletusaz Thanks so much!
When the content creator says "dislike if u dislike the video" you know he's hella confident. That's when you must like the video (if u like it of course).
LOL thanks so much :)
Thanks for sharing your test results!
I completely disabled rolling cache and suddenly I got rid of sutters. My FPS stay the same, but I used to see hickups here and there, and after disabling rolling cache, these are gone and it feels smooth. Additional fact for me to aggree with you that rolling cache is broken, and if anything, it only adds for additional processing going in the background that causes stutters to me. And I have quite a good connection.
Good to hear Sergio!
Thanks for spending the time to do this. I embarked on a similar test myself and spent hpours and hours only to have my cache go odd and I had to manually delete the .ccc file in appdata (windows 10)
Yeah they have some work to do here, clearly. Basically, only the manual cache seems to work and if you want to see photogrammetry generated imagery you must use it to cache the appropriate areas. Thanks for the comment Ian!
Where exactly is the. Ccc file? Can't find any date in my standard folder.
I want to completely delete the manual cache but it's just not possible for me
@@axp2579 Where is install your FS2020....you open WpSystem, clic 6 x, open Localcache where you will find ROLLINGCACHE (it's the CCC)
jpvanderhaegen my rolling cache folder says it’s empty? Any ideas?
Wow. Very surprised. Thank you for testing. Hopefully they fix it soon.
I will re-test all of it when they make an update.
Great presentation.
I found no difference with Cache either.
Also appears that there's not much graphical improvement between med and high...even less difference between high and ultra.
I turned Ultra off for the speed benefit of high setting.
Could probably run at medium in some areas.
Sure hope they use photogrametry for more airports and cities, although I think they purposely left out many cities to allow payware a reason to exist.
Indeed 3rd party involvement was clearly a part of the design with this sim and it's API.
Rolling cache works: While online slew (yes that slew) around the area you want to cache (from lowest to highest altitude), change settings to offline, and fly. The graphics are now as sweet as being online. I'm sure rolling cache gets pretty fragmented since it can only "roll" based on the size of the cache. One area could be spread across the file therefore the larger the file the more fragmented and sluggish things can get.
Thanks Corey. I did not try slew and that is a great point. I will test that again this week.
Manual is the way to go. Huge game changer. I have no problem taking a few minutes to make sure my flight path pre loaded in the heavy GPU areas.
Great tip!
Excellent info!
Thanks so much!
very helpful , thank you
Glad it was helpful!
This is misleading. Rolling cache wasn't designed to be a performance booster. Its simply a folder that stores the data of scenery you streamed during a flight. Once you hit your designated cache limit that can be set manually, it deletes the first area you downloaded and stored. This happens automatically when this is turned on. Saying that its broken because it doesn't add any performance doesnt make sense. It wasn't designed that way.
It did not change any aspect of the sim. Not performance or appearance of scenery online or offline.
@@badGamr but it does save on data usage. Which is it's intended purpose.
Flying around New York I can see the graphics improve in front of my eyes as the data loads in as you fly along (and I can see this data download in task manger) and if I then go back to New York the high quality graphics is already there and I can see in task manger that no more data is getting downloaded so for me at least the rolling cache is working. I've also done some manual caching and again when flying over manual cached areas I can see there is no data download but whereas I can when flying over some non cached areas. I think it just really depends on which area you are flying over as the quality in bing maps is very inconsistent between regions. Manual cache is very bugged mind you, I cached the whole of the UK in Low detail with large parts in Medium and although I could see many gigabytes of data where actually downloaded the value for the region in the manual cache setting only shows it as a few megabytes (even though it now no longer downloads more data s you fly along) The biggest pain for me though is adding areas to the manual cache as it's painfully slow to do anything once you've already added and area. I'm enjoying FS2020 but with all the silly bugs I just wished they waited few more months before releasing it.
Very interesting. It’s clear they have a lot more work to do here. I agree they should’ve waited longer to release it
That's why I was kinda surprised that they released it already, I was thinking maybe at least by the end of this year. Feels kinda rushed.
@@mackymac5754 I agree. As I said in the video I think they put this out way too early. Personally I would rather wait longer for a product than get it sooner and half-baked. Thanks for the comment Macky!
badGamr Just guessing but I suspect the release was set to gain a better market share over p3dv5. Knowing many would spend lots of money on v5 they knew it would reduce the available funds for 2020. So they released it now as a WIP and snag the market before v5 could really take off. Just my guess but it seems to track
@@brianpriest2930 you might be right, Brian!
I've got an old cpu (waiting for next gen) and a decent internet speed. The rolling cache and manual cache works as it helps with the loading times and doesn't have to wait for internet to download the area. Cache has a big impact to my gaming experience.
big impact .... what impact ?
@@jpvanderhaegen there's no stutter in loading areas on cached ones. Bear in my mind I have and old quad i7 cpu and a 50mbs internet. So cache helps. When I dont cache a new area, the game freezes for a couple of seconds while loading the area and it's not good when I'm flying low. *edit - sorry I got distracted writing.
Good to know. It had zero impact for me - Internet connected or not.
The easy way to see if cache helps is looking on the size of the file, only major citys on usa and europe got high quality stuff, even on usa some places got far better quality like new york, 8gb download on very small area on new york, other areas files are much smaller, if u see building/terrain changing format on your face, going from blur clay to pretty stuff u must be on a high quality area, pre cache on those area make a huge diference.
I'll give that a try Eric! Thanks!
Thank you very much for the video, I can stop ripping my hair out now.
You’re welcome 😊
badGamr hey I just finished uploading a video to help people who purchased the Steam version with getting there simbrief flight plan into the simulator. hope you don’t mind I mentioned you in the comments and linked your CZcams.
@@PowerAirSimulations No problem at all Steven! Great video too!
If you look at how much memory is used on cached areas outside of photogrammetry it is obvious that it can't do that much. Maybe the heightmap is slightly better and maybe the textures of the ground get slightly better, but AI generated buildings will see no impact at all on this.
I found an area of 10x10 km will need only a few MB of manual cache memory. So you could easily download this on the fly even with a slow connection.
For photogrammetry it's a whole different thing. The LA area is several gigabytes in data. So low/med/high should make a visible difference there. That said photogrammetry always looks kind of bad up close. It has not only buildings, but also trees and cars as heightmap data, which has a far too low resolution to depict it in a realistic way. Textures are blurry, too.
It's a nice advance in visual technology but I agree it's painfully clear they have a LONG ways to go with it for close up. At 1500 ' or higher things look decent though. Thanks for watching :)
Well done
Thanks!
So you have to do manual cache in such areas either low medium or high that way the graphic is always there when you’re flying over a certain area and not in blocky form and loading while you’re flying.
It only uses manual cache data if it cannot download it from the azure servers. I did a followup video on this topic here: czcams.com/video/GbWpaEzZUYs/video.html
Great Video - Has it been fixed it?
I have not re-tested yet. Planning to look at it tomorrow afternoon. Glad you liked the video :)
My only question is how are you running a Win10 program on a Mac?
My favorite youtuber Brickette set it up for me using something called Bootcamp. I actually run it off of an external SSD.
Caching is broke for me too. After (trying) to use it the for the pas week on multiple areas my conclusion is that it doesn't work. Been caching numerous area between medium and high quality in different places around the world. Didn't change a thing and sometimes it takes close to an hour to be able to cache a 2 Mo area...
Tried to cache in high quality city with photogrametry today (Quebec city). Didn't work at all...had the same AI buildings than my previous flight in rolling cache. I have a low internet connection so was putting a lot of hope on pre-caching...little bit disappointing for the moment...hope it is fixes soon.
I think this is a pretty big issue and I have high hopes that they will address it quickly.
Rolling or manual cache isn't broken - it's there to save on data useage, hard drive space permitting. That's it. The scenery generation is the same if it's streamed live or saved on disk.
Actually you must use manual cache in order to see the photogrammetry scenery as I illustrated in this video by showing Seattle with and without a manual cache. The visual difference was significant.🙂
@@badGamr this is not true. I always see photogrammetry scenery where it exists, and have never used manual cache. Also, rolling cache works perfectly, as I have observed the lack of scenery download when flying repeatedly over the same areas, including New York City.
You guys are correct. The only benefit of rolling cache is to save on data usage. It's not to improve performance. Photo mode also works with rolling cache. Manual cache is just for areas you never want deleted.
I don't know about you but I'm planning on testing out the weather system when hurricane Laura hits the Louisiana/Texas coast!
Love to see your video of it!
@@badGamr Haha! for the sake of the community I wouldn't wish that waist of time on them, best leave videos like that to the pros :)
0:54 - I have ms2020 in bootcamp. did you setup your ms2020 in external ssd? Thanks for your videos.
Indeed I did.
@@badGamr glad to find bootcamp user. :-)
@@ychoi07 It CAN be done! :)
Ahh this is interesting, so just to be clear did you mean that manual cache is what adds photogrammetry? And that it does not add photogrammetry In some unsupported parts of the world (such as Paris)? I wonder if anyone has made a list of current areas manual cache works...
That is exactly right. Here is a list of the cities: www.rockpapershotgun.com/2020/08/18/all-341-photorealistic-cities-in-microsoft-flight-simulator-2020/
badGamr holy cow thanks!
I'm not so sure about your angle here.. I've not seen MS/Asobo mention performance improvemens, but rather an option for those who are on metered connections?
The bottom line (for me, from my testing) is this: Rolling cache does nothing. Manual cache allows you to see scenery that has been generated with photogrammetry. That's it. I am not the definitive be-all end-all on this topic by any stretch and certainly my testing could be flawed. These are the results that I observed. YMMV..
@@badGamr Cache has nothing to do with the image quality, but you being able to let the game get the data from a local cache, and not stream it from Azure - that's what the actual word "caching" means....
What you really should test, is you bandwith usage with or without cache...
Its function is to save download amount which means you don’t have to download the same area again and again!
My testing showed that it had zero impact. There have been a few updates since I made this video and maybe they have improved it.
I thought the purpose of cache was to give you bing graphics when you don't have internet. But when my internet was out, i found i got no bing scenery, either from areas i had rolling cache, or from areas i had manually cache. That is the main reason I want cache, to get bing scenery without internet.
I’m not convinced that cache does much of anything
the guy is running the sim on a MAC.. (on a MAC?? that machine is designed for text, and video until 2011 :)) ), sad, nice vid by the way :) and awesome voice
Thanks for the kind comments. As to the mac, It actually works pretty well. Not ideal but it gets the job done :)
My 30+ yrs of simming..At least once a month even weeks, someone post they have found the Holy Grail of tweaks and everyone jumps on it. Just as quickly as the miracle setting appears it is proven to be a placebo or a roundabout way to lower a setting.
Upgrade to a modern system and if you can keep a steady 30-60 fps FLY IT. Let others do the marathon tweaking and buying $1600 cards.
Thanks for your input.
Did it help with stuttering at all? I noticed on my system (3900x,64gb ram,2070S ftw3 ultra overclocked) I get stuttering or pausing on occasion when it seems to be loading or generating scenery or new regions. And I don't mean stuttering where it turns into a slide slow or something while turning. I mean just flying straight and level every now and then it will pause for like half a second or something every now and then. I was hoping increasing my rolling cache or using manual cache would fix that. I also have a fairly fast connection (250 down). And as you stated manual cache doesn't work with regular sat images so that won't help me any in rural flying over Michigan and Ohio. Only over larger cities like Detroit and Toledo. I hope they fix that at some point.
I get the same issues. Caching has no impact on it. I think that is a quality issue with FS2020. hopefully they will patch for this soon
@@badGamr You are correct, I just tested it. I ran it like I normally do, online mode, rolling cache on. Then I put it in offline mode and rolling cache on. The only thing that changed is it didn't do the voice atc thing anymore and I didn't have to ask for clearance to land or any of that. Everything looked exactly the same with the same performance. Most likely because that area was already in my cache. Then I turned off rolling cache. With that off I lost the fancy sat images. Honestly it didn't look "bad" though. Just didn't look exactly like where I actually live. For instance in one spot there is a big stone quary near me. With the cache on it renders it correctly and looks amazing. With it off the depression and hole is there but its mapped with houses and stuff lol. And performance was not better either, actually it was a bit worse! Frame rates dropped by a few fps over all, but were more constant. And I still got the same little random stutters and pauses, in the same exact places! How odd is that. So going to a manual cache isn't even going to fix the issues I wanted it to. Must be an optimization thing or something. Hopefully they will work out some of the kinks in the months to come. I think the pushed the release a bit early to be honest.
hi, im really curious. are you the voice on wwyd??
Nope. Sorry 😊
I do a manual cache download a small City around 1 gb , then I turn internet off and all I get is the basic graphics, the manual cache doesn't show , real life being data only shows when I'm online, I'm going crazy trying to make it work offline.
Yeah I think the cache is broken tbh. Hopefully they address this issue very soon.
Here is the reason why the rolling cache doesnt work for many people:
Yes, the game creates a huge block of cache, lets say 500GB.
But it barely writes to the cache or load from it. So it doesnt use the cache atm.
I agree. Another thing they need to fix. Thanks for the comment Waldherz!
it works WHILST THE GAME is loaded still.......but when you restart the game, and try to use a manually cached area cached in the recent game session with roaming cache turned off throughout.........the manually cached area IS NOT CACHED anymore. Literally it forgets its even cached even though the area cached still show in DATA > MANUAL CACHE and the list of cached areas.
Thanks Dazzer. I'll check this out!
I just fired up the game and went to each of the 6 locations that I have set manual cache for and all of them worked correctly. Are you on Steam by any chance? My copy was purchased via the Windows Store so maybe it's different.
if you turned your internet off and there was no difference, sure that means the cache was working as it would be worse without internet unless the cache was there to feed off, no?
I did it with cache turned off as well...
Which places exactly have been generated photogrammetrically? Is it the hand crafted airports?
There is a link to a list in the video description. But here it is just for you :) - www.fanbyte.com/guides/a-complete-list-of-all-photorealistic-cities-in-microsoft-flight-simulator-2020/
@@badGamr thanks buddy
@@dy8576 You bet :)
If it was Google maps not Bing. Both the quality would be better.. and there would be 99% of the world covered. The photogrammatry has alot of work to be done though. They could have made the buildings look more crisp and not so blocky. Especially since they made people want to low fly more.
I thought the cache feature is intended to simply reduces amount of times the software downloads the planet rendering data, no sense reloading an area every time you fly there if your continually flying in the same location. I don’t think it is intended to improve FPS but to save a persons data limits imposed but some internet providers.
You said you unplugged your internet for part of the test and nothing changed.... I think that’s the whole purpose of the cache, to remove the reliance on the internet connection.
Came here to say that, the purpose of the cache was never to improve the pefrormance.
There was zero difference in terms of performance connected or not. If I had the cache turned off and disconnected the internet then connected it no diff - turn cache on - again no diff.
@@badGamr You would have to check your internet usage to see the difference, not game performance.
@@SunDevilPilot Fair enough.
After upgrading my cpu I don’t have any stutters at all. it’s all gpu bottleneck now so although I’m getting 30-35 FPS it’s feels smooth
Awesome! I'm jealous :)
Really? Even the 10900k is bottlenecked certain places here so what on earth did you get? :p
@@badGamr If you need to take load of the CPU turn the sliders down under the traffic options :)
@@tmkongen Thanks! I was actually aware of the traffic options eating FPS :)
tmkongen I got the 10700k, I have all traffic at 100 and object and terrain distance at 200, and in every area of the game I have tried, the highest my cpu load has gotten to is about 50-55%. With the in-game Dev Mode FPS Counter, I will occasionally get the signal that my cpu is the bottleneck, but it will only last for half a second or so and go back to gpu bottleneck.
The Cache wouldn't make any difference in regards to fps or quality .....what cache is used for is minimize data downloads, the places.....places u visit often in cache so system does not need to keep downloading same information every time you need it.....Now i am not an expert ....nor do I claim to be but this is what i understand of this specific feature ......any thoughts on this?
Check out my latest video where I use manual cache to improve the ground textures in the KVNY region.
@@badGamr thanks, I'll definitely check it out.
@@badGamr Thank you, so much for your help, finally got it to work and your video was spot on!
@@saish57 Glad it helped!
Always wait before purchasing new products... marketing people know how to rush things...
That’s true. It’s always a risk for us early adopters.
i have high hopes for this game in the next year but for the moment, i’ll have to be content with a beautiful but incredibly flawed experience.
I agree. It was released before it was finished IMO.
badGamr despite all the bugs, I’m glad it released when it did. The place I live went into a second lockdown and it’s been an extremely depressing couple months until this game popped up on Game Pass. Never having tried a flight sim I decided to give this one a go cause it’s “free” so why not. While going for my first flight and seeing the beautiful vistas, I smiled for the first time in weeks and it’s been helping me cope ever since. This game came out at the time I needed it most :’)
Caecario Wardana i’m really glad it has helped you so. i’m not sure where you live but i’m in lockdown too so i know your pain. keep enjoying the sim. it’s such a feeling of freedom at the moment (when it works).
@@jollyrioger2572 That's so awesome! Stay strong! We will get past this horrible disease!
Still broken in 2022.
Shouldn't all capital cities get special treatment instead of a recreation from a 2D image?
I agree that they should. There are cities with populations of 7000 people that got photogrammetry treatment while those with millions (Paris, London etc.) that were ignored. I hope they update these bigger cities.
Your internet or visual settings are off big time for Seattle. That looks horrible. Here I posted the same location with photogammetry turned off, no manual cache for the area, but rolling cache on. Same spot as your 3:00 mark. steamcommunity.com/sharedfiles/filedetails/?id=2219276410
Interesting. Thanks!
The only issue is see is you're gaming with a Mac. ;)
LOL well, in my business (video marketing) it's the platform of choice. :)
with 1gb connection you don't need cache
sounds luxurious :)
@@badGamr not really, im playing with a 4790k and a 2070 at 1080p lol

I would say that depends on how it performs while streaming or rendering the data. I have 250mps down, which is plenty fast for this sim. They suggest 50 on the high end side. I still get occasional stutters when its streaming scenery and rendering it. I was hoping manually caching it would fix that problem.
