Add: 'Graphics Setup' stage > Nvidia Proprietary drivers:

The installer now supports enabling a feature that allows low latency display interrupts
to be serviced even when the system is under heavy contention.
This is especially useful for reducing stutter when using virtual reality.

This feature is experimental and disabled by default.
