Hi all, below is my profiler output for a packed build of a game. Every 5 seconds or so, there is a frame drop from 120 fps to around 60. The timing of it happening is regular, so it does not appear to be related to what is happening ingame. It is a PCVR project on Quest 2.
In the profiler, it appears as if everything is ‘waiting’.
Does anyone have an idea of what could be causing that frame drop? I’ve added a zoomed in version and an wider overview.
Long shot: which engine version is this?
I forgot to mention that, It’s 5.5.4
Ah, not what I thought then…
I figured it out after all. It seems that it was being caused by the Windows setting “Hardware Accelerated GPU Scheduling”. Switching that off fixed the issue. There are significantly less frame drops now, almost none.
Windows… If they just tried to write a decent operating system, instead of trying to sell something, we’d all be in a better place…
