    Not sure if anybody else has had this issue before, but I've been trying to profile my game on 2019.3.0f4 and it slows to an absolute crawl with Gfx.WaitForPresentOnGfxThread taking almost 400ms per frame - with the profiler disabled it gets an easy 100FPS

    I guess this happens while profiling Playmode?
    Where are you getting your FPS stats from? (Note: the stats overlay of the game view substracts time spend for Editor code, the Profiler does not)
    Does this happen while the ProfilerWindow shows the CPU Usage Timeline view or Hierarchy view and what happens if you select a different module?
