Let's discover the true potential of Unity by pushing its limits. In this video, we'll explore a variety of techniques, from straightforward tweaks like data-oriented design, to more advanced methods such as direct GPU rendering and compute shaders. Join us as we uncover the power and flexibility that Unity has to offer!
Some techniques used:
Unity DOTS (burst, jobs, ecs)
RenderMeshInstanced
DrawMeshInstancedIndirect
Data-Oriented Design
Avoiding extern calls

Let me know if you'd like to see anything else benched, or whatever else you'd like me to cover :)
My specs:
Ryzen 9 5950X 16-core
GeForce RTX 3090
64GB Memory
How about the forgotten Quaternions?
Sure, mesh baking vs instances vs gpu instances, material batching, light baking, all these stuff. Also triplanar mapping with 3 textures, with 6 textures (albedo+normal), simple vs. with blending. LOD solutions: unity lod, vs other solution (like progressive mesh) + billboard + impostors. All these are very interesting.
There's no way my laptop with 12 fps on blender has quadruple your space with half of it being free and STILL only runs at 12-25 fps on blender.
Hey, cool video. I think you could squeeze out more performance out of mono behavior game objects by parenting them to some object.
Maybe add that as a benchmark case. I believe that incorrect hierarchy might cause a few % slowdown.
Wait, I don't get it. Are you mental checkpoint?
I love how you prepare all these scenes to make them look so appealing and eye-catching for us. Good stuff, keep this up! 😛
The poor bitrate couldn't keep up when it reached 90k cubes ><
Glad you enjoy the visuals :)
Increased Performance Strategies :
1:30 - Manager script instead of monobehaviours (only 1 Update() call)
2:49 - Reducing external calls (Caching position instead of asking repeatedly the transform position)
3:50 - GPU Instancing
5:21 - Multi-threading (Unity "Jobs" & "Burst")
6:58 - ECS (part of Unity Dots)
8:29 - GPU Instancing Indirect
13:09 - Camera Cache
Awesome. Thanks ❤️
You're welcome and thanks for helping Unity devs ! 😉
I'm having trouble with rendering 9 chunks of 16x16x10 cubes for a simple prototype (I didn't find the way to implement simple GPU instancing..) so I don't know yet how to use all the work you did but it seems really great !
Man, I really want to get into DOTS. Really seems like it's the future of Unity development.
More performance than you could ever really need, to be honest
I think it's not worth the cost of time & complexity for most projects
@@mrslake7096 Yup, 90% of indie games will never need to touch it. The ones which do will most likely only need jobs & burst.
Even for a game like vampire survivors, ECS is not really a requirement.
not worth it unfortuantely
@@MuhammadHosny0 it's absolutely worth it if you want to make games with multiplayer and mlagent ai. Infact it is necessary, my game lags so much without it, and I used a small count of very simple ai.
Yes without these 2 things, it's probably not worth it. BUT... dots isn't actually hard to figure out. The hardest thing imo in unity is multiplayer (but only because my game is complex), everything else takes a day to learn.
I'll have to keep this in mind. Love what you do for the community!
WOW!! This was a fantastic video. I've been dabbling in learning Jobs+Burst but this demo was just amazing, gonna have to put more effort into getting my head around that .
Your vids are amazing; fun to watch, very interesting and always filled with info.
Also love that you always include similar scenarios with the different tools we have available to show their drawbacks/advantages
your video is really great , help me learn a lot, and seeing 10k objects on screen at the same time with high fps is so awesome and fun to watch
I love these new test and experiment videos , keep it up man💜
wow! This blows my mind, and gives me a lot to think about and research. Cheers mate. great Vid.
GREAT VIDEO!. i really like these comparison videos.
very useful and descriptive thank you!
This one was fascinating mate, really liked the visually focused explanations, showcasing the tangible FPS improvement along the way.
Man! I think you are one of the best unity creators in yt..
Your explanation is clear and you really know what you talking about
I would love to watch a serie where you create a game from scratch using all those techniques
Every time I watch your videos I learn something new. A lot to try to understand but this is uber usable for my next project, Bookmark. Thanks.
Great work! One of the best gamedev videos I stumbled upon in a while!
That was rad. Keep up the awesome work!
You're one of the best devs in the pass it on challenge, awesome work man
So love your channel Taro ❤ it could touch my feeling again about development industry
This is massive, I'm making a satellite tracker that I've been trying to optimize forever and this is what I've been looking for, thank you.
Absolutely love this content. Thanks for taking the time to systematically clear these things up and visually show the difference.
No problem, it was a lot of fun 😊
Legend mate. Very insightful!
This is actually very helpful. I am currently working on a Game that has to update the position of many thousands of GameObjects. I will definetly try to implement some of these things to boost the performance.
Insanely helpful to see these steps broken down like this, thanks for the video :)
Great vid! :) Was always undecided over individual scripts compared to a single loop.
Amazing video, thank you so much for making this!
Yes, it was fun and yes, I learned something.
This is to be expected from Tarodev, but NEVER taken for granted.
Thank you Sir. Stellar as always.
Good to see you're still here, Tristan 😊
Awesome performance comparison man!! Very thorough 💪💪
The DOTS 🐐 has landed
Taro, you explained all of this so well!! I admittedly don't know a single thing about ECS, Dots, GPU instancing but even from that position, I came out of this seeing the real benefits of those systems. Awesome job and love having you back making vids :)
Ahh, thanks Nicky ❤️
i knew from jason weinmanns gamedev show that you should do your own game loop instead of the monobeheaviours and that ECS ist fast, but your video is like a massiv sun shinning light on this topic and helping me understand, 100/10 quality content! thank you so much
Fantastic - great examples!
Thank you! Thank you! Thank you! I never knew of GPU Instancing Indirect! Bloody hell, that is a game changer for our Voxel Engine, so glad to have found your video and can't wait to implement this indirect instancing. 😊
Amazing video again, I was wondering how to do gpu instancing and this really helped :)
You're the programmer with a great teaching and visualization skill sir. You're fantastic, After Breakkeys i kind of lost hope in tutorials but after discovering your channel you're indeed a blessing for Unity developers.
dis foo stuck in tutorial hell
This is really good. Please more!
Wow, its so mind blowing that often its not about the engine but the developer himself regarding how much can you extract the performance out of the engine.
Very insightful as usual, thanks a lot!
there is really not a lot of good in depth resources about doing GPU Instancing, it would be amazing if you can a video exclusively about that.
I can do that :)
@@Tarodev Please do good sir :)
@@Tarodev I'm gonna second this suggestion, the lack of resources is really sad, it feels like there's an abyss between a mid level Unity developer and an advanced one, because these techniques are only shown through examples but barely explained in detail. Please do! Thanks in advance!
What an excellent video! Advanced concepts, smooth implementation and succinct.
I'd love to have this exact same thing for Unreal Engine and to be able to compare both, but I see you focus exclusively on Unity.I've got a bit to learn about Unreal and shaders before I can do this but I definitely will at some point.
Thanks for sharing your knowledge!
I would absolutely love to see an Unreal comparison. UE is looking INSANE recently.
Awesome content, thank you!
Subscribed, just another very cool content. Thank you.
I learned something.
Thanks.
I love your videos. very informative.
looking forward to your next video.
DOTS are hard.
Amazing how you can write them as if its nothing.
I hope I can become a great coder like you one day~
if possible, please make more video on dots in the future.
or other performance related topics are fine too.
More DOTS? Can do!
Now subscribed, very useful stuff here! Thank you.
Waouh! What an amazing and instucting video ! Thank you so much.
Love these tests!
Some big surprises here, thanks!
This video is pure gold 🥇, thank you❕
love this style of incremental enhancement.
WOW! I downloaded the code, loaded it und followed you on this video. Can't believe it was this easy to follow along with you. Excellent set up of the software, easy to understand. :)
Awesome video!
Welcome aboard ❤️
Incredible video, well done!
Thank you so much! This is so helpful!!
I will treasure this video like Golum treasures the ring.
Thank you so much, the visuals and explanations are perfect !
Solid work, subscribing.
Welcome 🙏
Really impresive experiment!
Awesome video! It reminds me of Dyson Sphere Program, the devs offload everything they can to the GPU to get insane performance out of Unity
This is so well explained, omg I didn't even know that half the things I was already doing were optimizations in the first place.
terrific video! subbed
Welcome aboard 😊
Insane how big difference some of these technologies make. It really opens up options for new games or features while keeping really good performance.
This is the best AD for Dots and ECS
Man, I missed you!
This video is Amazing!
Thank you :D
Yessss a new TaroDev video, instant like.
Can we expect some ECS DOTS Tutorials?
This could be in the cards
@@Tarodev I was going to ask the same thing ! Just want to push this haha
ECS DOTS is dead. It’s never coming out. I promise you. Not worth investing in
@@gavintantleff I respect your opinion, but you can't just put your opinion as facts. I would like to hear some stats/facts/ research that can back your answer.
@@jubinjajoria2870 the fact that most dots libraries are not getting any real work done, there are no updates or information about dots, deadlines missed significantly. Of course I can’t know that Unity is dropping it, but it sure seems to me like they are. Why they don’t just come out and say it, I have no clue.
The only dots related feature that seems like it’s being kept is tasks and burst
Amazing Video !!
Thank you for just getting to the point.. my attention span is fried I was reluctant to even watch this, but you drew me in with the up-front examples this was awesome!
I'm catering to people like myself (and you), who don't want to hear the life story of the dev
Really great and intelligent video, I can tell you really know what you're doing which is refreshing to see on youtube :)
Glad you enjoyed ❤️
Very nice video, this is the way I always work, Test everything , learn the best practices, from actual experimentation. I’m caching everything, coded for years on mobile/ switch, and those caches have an impact on a 10 to 20 times, slower Cpu. Input. For exemple is costly, more on some hardware. Plus it’s not just the call of an external function, taking time, it’s also the need for the cpu to trash the data and code cache. Making the functions coming after slower, because of it
You just converted me to a DOTS believer. I didn't really care until this video + knowing some stable release seems to be on the horizon... :) I'm diving in!!
Thanks for this insight on performance! It's a huge aspect of development I'm personally interested in :D
If you need new topics, you could share tips to reduce the final data volume used by the build (sometimes I see games that take so many Go that I don't even understand how they have reached so much! Even considering a lot of textures midmaps and full assets integration).
Damn, that's a great video idea. It's something I could also learn a bit about, too. I've done this a few times on previous project deployments, but I feel there's a lot to learn.
Thanks for the video, very informative.
great video as always. super useful to get started choosing optimisation techniques. It's so tempting to implement ECS once it enters 1.0, even for just the sub-scenes, but it's probably way too risky for games that release within 12 months... >:(
Amazing!! Thank you!
Crazy, top video!
great content! thanks mate
thank you, I have learned A LOT
Great video 👏 It would be interesting comparing these techniques to using VFX graph.
cool, thanks for this benchmark
Video idea related to this: how to properly benchmark & profile. Recently there are new tools like memory profiling. A deep dive especially by you who has shipped actual titles would be very interesting. Thank you again!
Great job
Excellent video!
Awesome videos!
This dude always exploring the actually important shit. Thanks duder.
I haven't programmed anything in Years and never used unity but this video was still auper interesting:D. Amazing presentation:D
Im an indie game dev, who was working on a voxel game, and my biggest issue was rendering. This will definitely help. Thanks!
mind blowing . great video
Absolutely amazing
Caching variable does make a difference. Especially on mobile devices, where we don't have much rich instruments to optimize our projects, and we need to be sure that it work across multiply devices.
Another great vid. Would love more coverage of Jobs / burst.
eg similar but instead of a single cube maybe a raycast car (casting rays on each wheels) etc. Really hoping the doco/framework starts to cement abit this year
i not very good in English but the way you teach ..wow .! thank a lot Tarodev ..i love your video
Glad you enjoyed ❤️
The numbers just feel so good to look at because the font you use is the supercell font, which is just hilarious. Makes me think 12 fps is good.
tarodev is the real MVP
This was very interesting and I didn't know those APIs in Unity for GPU instancing yet
Thank you for everything that you do
You are most welcome
It's beautiful!
Great video, needs a follow up!!!
The most underrated technical tutorial.
Dude, that's crazy :,)
I can see myself using it for bullets in my top-down shooter game
This is mind blowing.
Fantastically educational
Fantastic video, thanks!
FWIW I do the same with Camera.main, transform, etc. But I've never gotten around to testing if it still makes a difference in a build with IL2CPP as that presumably takes away a large portion of the extern call cost
@@kylebanks The benchmarks in this video were all within an IL2CPP build :)
@@Tarodev Ah cool, well that answers that then :)
Absolute god tier content.
Hey Tarodev! Your videos are amazing!
Can you do a video on performance for mobile games? That'd be great.
Amazing!
