ah, so I think I'm reluctantly going to be returning my Q3.
Had a decent go in iRacing tonight, and the PCVR performance over link ain't half bad. Managed a smooth 90fps without any juddering which was nice, but a shame it's not 10bit as slight colour banding.
The main reason is the god awful mura. I've never seen anything so bad. It's like I'm wearing a really dirty headset all the time. Even in oculus home, the second you move your head you can see it all.
oh, and there's some trapped dust in the left lens. Come on meta!!!!
