I recently tested out the performance differences between my new 4090 and 3080ti with the Ryzen 5800x3D in my Quest 2.

I am using Gryz's complex benchmark mission to allow others to replicate my test method.

I disabled ASW in the oculus debug tool to get a true frame time graph with MSI Afterburner.

I'm running the headset at 120hz and maxed out the render resolution slider

In game, I kept the Pixel Density at 1.0 and always used the High Preset.

The improvement is pretty remarkable for very smooth VR performance. Ignoring the jumps at the end and beginning of the benchmark, the 4090 stays around 75-91 fps while the 3080ti only maxes out around 50 fps. It is a night and day difference. (See more info with MSI Afterburner by opening the .hml file attached)

With ASW enabled and using the VR preset, I rarely ever entered any sort of reprojection.
