VR play specifically benefits from a current-generation 16GB+ GPU, and VR controllers are not supported (HOTAS/joystick expected). DLSS and FSR upscaling are both supported and confirmed compatible with VR mode, following real, extensive development work (including roughly 6 months of collaboration with NVIDIA) to solve dual-rendering challenges specific to combining upscaling with VR under DirectX 12.
