- In this episode we cover the steps required to identify the cause of your frame rate drops. We go into more detail about CPU-related frame rate drops, using the profile tool.

Amazing, thank you.
Okey, can fin the file in \Saved\Logs\profileViz, but, how can open ?
@@HipernovaGames got the same problem.. shit does not work
@@Skalbemann yes the same, can't open this log file
@@Skalbemann found the way - open an empty 5.2 project to see this log
Underrated video, I wish Epic had a bunch of videos like this, short and too the point! I'm glad to see this at the top of Google's search results when searching for UE5 profiling.
This is exactly the performance tests video i always wanted to see.
Thank you!
This is so relevant for me at the moment, much appreciated.
Thank you so much for this video, short and sweet! 👏👏👏
Very helpful, thank you so much for posting this!
Thank you so much for the video, it's exactly what I was looking for! :)
Wow! Totally helpful. Subbed.
Great resource, thank you!
Very useful, thank you!

Great found it save the log but now its not showing up under profile log its empty ?
Thanks
Thanks for the video.
Have you ever attempted to create a mobile version of any of your games?
I tried with my first game, and it was challenging due to very limited resources. Despite the constraints, I managed to achieve results somewhat similar to the original.
The process taught me a lot about optimizing my new games
Nope, I'm a PC man, through in through :)
ok tried again still not showing did find it but notice on yours its a uestat file like a square paper looked for mine its a folder when i open folder nothing there? is there another way to find it? also most of mine are all show GT tickable time tickablegameobjects time tick time ?
yea there something yet again work with my engine it shows nothing folder is empty it figures been dealing with set back for the last 3 year with unreal if its not one thing it another
I see CPU Stall at the bottom of the GameThread hierarchy -- not sure what it means or where else to look.
Thanks for the video
It's stalling for something- meaning there is something processing (probably GPU) before CPU processes again. Check your detailed stats in editor (when playing) and see if it's the red line (CPU) or another line that's the highest
Interesting. Just when you think Unreal is the most complicated thing in the universe, you realise it's far more complicated than that.
But, good to know and helpful, thanks.
For loops have terrible performance in blueprints because they are made out of other blueprint functions(they are macros). So, if you can do checks like this in C++, it'll run 1000 times faster. I think Epic is pushing Verse because blueprints based on it will run at near native speed. Theoretically, blueprints should run just as fast as C++ (they are really easy for a human to 'compile' into C++, so the editor should also be able to do that automatically). It's is a real limitation of the engine.
Thank you- sounds like you know much more about this than I do
Unfortunaly i cant find a "Profiler" tab in Session frontend. UE version is 5.3.
Sad to see it looks like 5.3 might have retired profiler. 5.2 it's still there. Unreal Insights is the replacement- though I haven't played much yet with Unreal Insights.
On the bright side 5.2 still open profiles created in 5.3. But we will both of engine version need to be installed in order to be able to examine their contents. @@NumenBrothers
As the pinned comment says its now located in UE 5.3 at:
Tools - Profile - Profile Data Visualizer
@@codyozgaming9416 the problem is that the file type needs to be (profviz) in order to open it. I think using 5.2 is the way to go to open profilers files.
@@max3116 To be honest Unreal Insights isn't that much different, it just has a lot more functionality which seems to scare a lot of people.
What an unfortunate timing with 5,3. This video shows a real bottleneck and a way to find it. No such video for Insights exists, it's just hours of Epic guys talking about nothing, no real problem resolution. The info how to use Insights literally does not exist on the internet.
I have on my side 3 tabs Console automation screen comparison no profiler tab?
check out the pinned comment: Tools -> Profile -> Profile Data Visualizer
the new engine very new is not showing what you have on screen must have been a update after you made this video
Does not work in ue5.3
check the pinned comment
Why not show us the array and bp work?
If I release a proper game in the future, I'm sure it will be appropriately dissected and critiqued. And if it fails, then I don't have to waste your time with my array and bp bumblings ;)
thx daddy
