I’m in the process of optimizing my game, and I can’t seem to get rid of or understand certain line items in the ProfileGPU output (ctrl + shift + ‘,’).
The main ones in question are:
- Tonemapper #0
- PostProcessWeightedSampleSum#(There have been up to five of these with different numbers)
The only post process effect I have is Temporal AA, EVERYTHING else is turned off in the post process volume (I know I have to click and set them to 0). Knowing that, why do I have nearly 70 milliseconds going to all of these PostProcessWeightedSums? Also, why the Combine LUTs when I have that explicitly turned off?
As for the downsample, what causes that? Is there a way to turn that off? I’m running my program at hmd sp 137 (VR equivalent to SP of 100 for normal monitor). Why would it be downsampling?
Finally, why is SlateUI showing up, isn’t that supposed to be the editor UI? It still shows up when I profile in a packaged game.
