What concerns me re higher resolution though is the PC has to then be able to drive it. Its a struggle now where only a 4090 can really drive the Q2 to its upper limits.
That's the thing isn't it. It's why I like the Quest Pro as the resolution is technically slightly less than Q2 but it looks massively sharper.
Of course you don't have to max out the resolution in PCVR to get the benefit of pancake lenses and reduced SDE.
