I’m looking at ways to improve an Oculus archviz scene. Its a house; an interior with surrounding landscape. I set a fixed frame rate of 90 but the fps is 45 most of the time.
Looking at the profiler data, the cpu is waiting 22ms for the gpu. Stat gpu reveals that almost 40% (8ms) is used by ‘composition PreLighting’.
Anyone has an idea what this is and what I should be looking for to improve this ‘composition PreLighting’? I already searched Google, this forum and the Answerhub.
My guess was ‘dynamic lights’ but I changed those (one lightsource for the sun and one skylight) already to static.
Using 4.15.1 & deferred renderer.
I’m curious about the ‘composition PreLighting’ in stat gpu, although not specifically for vr. I’m also a bit curious about the [Unaccounted] item in stat gpu as well.
i selected existing PP volume and turned off all AO settings or disable whole PP - comp prelighting goes down by half - from 2 to 0.9ms. But where is another 0.9 ?
