GPU performance tuning of "HZB SetupMips" (As seen in GPU Visualizer)

So, 33448 is somehow marked as “fixed”, and yet…

4.16.3, the most recent engine version, so all fixes should be implemented.

What’s also peculiar, is that I get solid 60 FPS at the beginning, but then it starts dropping, fast at first, then slower, dropping maybe 1 FPS per second, until it hits rock bottom of 10 FPS

EDIT: I disabled two random widgets, and now the FPS goes well above 100…
Yeah, I have no idea either.
