This option looks to be something that could be of great benefit and looks to be handled by the GPU, not sure what it would take to implement in game or even if possible but still interested if anyone knows more about it? When i select it in the driver it says Not supported for this application!! Is this DDFR that is used in the Open XR tool kit? Variable Rate Supersampling (VRSS) expands on Turing’s Variable Rate Shading (VRS) feature to deliver image quality improvements by performing selective supersampling. This can also be selectively engaged only if idle GPU cycles are available. VRSS is completely handled from within the NVIDIA display driver without application developer integration.

I wouldn’t have cared about this last week when I was still in my 1080 Ti. I’m fully interested now though!
I haven’t done detailed monitoring and stats testing, but I’ve not encountered any noticeable issues so far. If I was flat gaming in 1080p, I would run into CPU-bound issues, but VR is much higher GPU load by default, so I should avoid that. I need to run the diagnostic to how much overhead I actually do have.
