Hello! I am currently struggling with frequent low fps drops with almost no graphics added into the scene. Specs are: UE5-0-1. MacBook Pro 16’ 16GB, Radeon Pro5300M
Standard levels seems okay’ish in terms of performance. My current scene has very little in terms of actors added (they all are super low-poly models as well). When I looked up into GPU profiler I have seen this:
In this case fps are dropping to around 5-10 fps. Average FPS through out the work session is around 15-17. But sometimes when I do literally nothing FPS goes up to 70-80, after what slowly going downwards.
When I open EU5 early access with metahuman project, average FPS is around 60-70 and seems to have no drops.
Would be glad for any advice of how can I fix this issue or what (where) should I search to know the source of the problem. Thanks!
Translucent materials would probably be a good place to start
I didn’t setup any materials manually. There are only a few new ones that were imported automatically with low-poly static meshes.
I have searched and filtered all materials in content browser and I found 0 materials with translucent blend mode that are in the scene. Therefore I still have no idea of why this is happening
UPD: After leaving editor opened for a while I now see “Texture streaming pool over 29.000 MiB budget”. But frames are decent between 37-39
post a screenshot of your scene in the area where it is slow
That is the whole level I have. Frames are becoming low randomly both in editor and while playing regardless of where the camera is facing
What’s the shader complexity view look like?
Edit: Also does this issue occur if you launch the game in Standalone? Or package it?
Here is shader complexity view:
Didn’t tried to run standalone or packaged. Will probably need some time to watch over this behaviour
UPD: Just have faced fps drop again, tried out standalone and it seems like nearly 60 fps (didn’t see the actual counter thou)
