    I am seeing intermittent spikes on the gpu in deep profile from FixedExposure:

    this being 23.27 ms on a RTX 2080 ti. I am curious what might be causing this? even when I turn the fixed exposure off, I still see the spikes.

    @EdBoon just curious, does the same happen with an empty scene? You didn't mention what your test case was.

    Must have missed this back in March, I'll try to check when I get a moment, the scene was pretty complex where I was experiencing it.

    I can't remember what conclusion I arrived at, but I think it was something to do with MK Glow plugin. I'll try to look into it again and see if I am still getting this. Also, if you find anything else out, I would love to hear it. Thanks
