My profiler shows drops in the Frame Time from ~31ms to <1ms precisely every 30 frames and the whole scene stutters during this frame. Idle Time which is normally ~30ms also drops to below 1ms.
What confuses me is that I’d expect some script to load the system during that frame which would cause stuttering, but as you can see on the screenshot - nothing of note happens during that frame, if anything, less stuff is happening than in a normal frame.
I will start backtracking my recent commits since it seems to have appeared recently, but does anyone have any idea what might cause this behaviour in theory?
