Post Processing has a big performance penalty when it present in the world and even disabling all Post-Process Volume components does not restore performance fully.

To gain maximum performance boost it's nessesarry do disable Post-Process Layer component attached to player camera.

Please add Udon hook that will allow world creators to toggle Post-Process Layer component so people can completely disable Post Processing in the worlds with in-world toggle buttons to gain as maximum performance as possible.

Added performance test results captured with SteamVR Advanced Frame Timings window.
