Cyberpunk 2077 with the VR mod is the only one I can think of. Because it’s not natively built for VR you have to render the world separately for each eye leading to a halving of the overall frame rate. And with 90 gps the bare minimum for many people in VR you really don’t have a choice but to use the 5090.

Yeah it’s literally only one game/mod, but that would be my use case if I could afford it.
