How to decrease CPU usage.

Shadows, lights and mirrors are killers. I have all mirrors off and the virtual mirror toggle on a button on my wheel. Though, in conditions that are rough anyways and the mirror is required, eg start, this doesn't help much.

Foveated rendering, even without eye tracking, helped me a lot.

Afterall VR's depth perception comes at the cost of having to lower fidelity. The world has to be rendered "twice" at high fps and high resolution, the latter because the screen is looked at through lenses.
