UE5.5 Bad performance. Strange Unreal Insights graph

Development Programming & Scripting Blueprint

We recently update from 5.2 to 5.5 and havn’t really changed anything, but are getting really bad performance on Android.

The strange part is, our unreal insights data looks odd. Our total Game and Draw times are what we expect, but then we have a bunch of other WaitForTasks just doing nothing. Theres large sections of these WaitForTasks with no other threads executing anything.

Another strange part is that when I press F to focus on the frame, it encompasses two different frames. Its focus starts late in one frame, and extends well into the next frame.

Overall I’m seeing an extra 10ms or so of frame time that I can’t account for in the graphs. I’m not seeing this on windows or editor builds

Any help would be appreciated!

I think you mean “Two differents ticks”.

Your render thread has a single frame of 31.7 ms…
i think something heavy is drawing on the screen in that moment.

Scroll down… maybe is loading PSO… if so you will need recolect PSO to precaching.
