Hello,
I am currently focusing on tuning the performance of my Oculus Rift VR game and have noticed that in the GPU profiler text output I have a (relatively) massive item of SlateUI for more than 3ms.
Like so,
[2017.08.11-23.18.47:140][391]LogRHI: 38.1% 3.86ms SlateUI 1 draws 2 prims 4 verts
I’m checking this in a packaged/cooked build, and am not using any slatey 2d ui objects for my game.
If I do a printout running the exact same build in 2D desktop mode the SlateUI does not even appear in the list.
So my conclusion is that this has something to do with rendering for the HMD. Suspiciously also the description of the prim fits that of a simple quad.
Does anyone know what causes this and how I can get rid of it?
3.8ms is a stupid high amount of my 11ms rendering budget. (here 38% of frame render time)
Cheers
