GPU Profiler question
I'm using the ProfileGPU command, and I want to understand more of what these things mean, mainly:
PosOnlyOpaque Static EBasePassDrawListType=0
As they are the most costly looking things going on. I couldn't find this info anywhere in the documentation, so I unless I missed it somewhere, can anyone help me out on what these mean?

I'm having the same pain points. I don't see anything in the documentation either.
In a level with ~2M tris (15 fps) my PrePass Opaque is 18+ ms, BasePass ListType=0 is 21+ ms.
In a similar level with only 112K tris (119 fps), the PrePass Opaque is 1.36 ms, and BasePass ListType=0 is 1.32 ms.
From my comparison, it seems that these numbers are related to the rendering of triangles. Keep in mind, a different pair of levels, with a smaller difference in tris (105K tris vs. 305K tris), have similar PrePass and BasePass numbers.
Check your tris with [stat rhi]
