Do you see a lot of games that run well in 4k@120hz? VR is much more demanding. Maybe if you spend $20k on a box with 8 GPUs it will be able to run it. But it’s not just GPUs, you also need much better headsets (much higher refresh rates, 8k+ resolution, wide FOV, very good eye tracking for the foveated rendering, much higher dynamic range). Most importantly, creating all that photorealistic content is a huge effort, and you need a lot of it for VR. How much are you willing to pay for it?
