Oculus Rift VR - NVIDIA vs AMD

[Ian]

Babel Tech Reviews have an interesting set of benchmarks that compare the VR performance of the Oculus Rift on NVIDIA and AMD graphics cards. It's important to note that even an incredibly expensive GTX 1080 Ti can't run some VR games at the highest presets:

Until NVIDIA released FCAT VR in March, there was no universally acknowledged way to accurately benchmark the Oculus Rift as there are no SDK logging tools available. To compound the difficulties of benchmarking the Rift, there are additional complexities because of the way it uses a type of frame reprojection called asynchronous space warp (ASW) to keep framerates steady at either 90 FPS or at 45 FPS.

Both NVIDIA and AMD agree that Fraps benchmarking only provides a slight correlation between what the user actually experiences and what is displayed by the Windows desktop. Fraps only measures the framerate of the desktop window, not what appears in the HMD so the performance that a user sees in the desktop window is not a valid proxy for the experience in the HMD. OCAT, Performance Mon, Afterburner, and other PC benching software do not accurately report nor measure what the user experiences in the HMD. And it is important to be aware of VR performance since poorly delivered frames will actually make a VR experience quite unpleasant and the user can even become VR sick.
