I am not an expert in VR, but I know one of the main causes of sickness from VR headsets is the latency between the user's head movement and the simulated camera movement. Basically, there is lag between when you move your head in real life to when the VR headset displays that new view angle to your eyes.

Reductions to this latency is an ongoing effort and companies like Nvidia are definitely in that space.

We already have infinitesimal latency thanks to predictive tracking in both the high end headsets. The main source of sickness nowadays is vection.
