I've never tried VR. Assembled a new computer with a 3080 TI and ryzen 5950x, so I think my build should be able to handle just about anything.
Seems like Valve Index is what I should be getting right?

Is it difficult to get used to it?
Do any of you guys get headaches using VR?
Do all VR games generally support all VR headsets?

I guess it's hard for me to imagine what it's like in general since I've never tried anything like it

Is it very immersive?
