profiling cpu/gpu stalls


I’m having some issues with performance, which (I think) is stalling on the gpu. Most poolthreads show a cpu stall, as is the game thread. Weird thing is, there’s hardly anything in the scene. The profiler is quite new to me, and I can’t seem to find the origin of this problem. It’s running ~30fps which is awefully low for a scene containing harldy anything.

Looking at the gpu profile it seems the prepass is taking up quite a lot of ms. Captures are taken with disabled smooth FPS, running standalone game instance.

Could somebody please point me in the right direction to find the culprit for the stalls? Thank you so much!!
