Probably wrong here but:
A few blurry reasons
Weak GPU card, 
Bitrate low meaning the game auto reduces your quality maybe ,,, and or weak wifi signal from your 5g.
The 'sweetspot' is small, many seconds of fiddling around with the strap etc and I could find some level of clarity I was happy with, I also see some blurriness in certain scenes.
But I could see why people never could reach the sweet spot, such as ipd being some wierd inbetween of ipd levels, and maybe depending on what face fit they have..

Some earlier q2 models meant that the quality was lucky dip, and there's a post on Reddit where people just received apparently straight up shitty lenses. There's some isolated text test that you can do to check if you also have something like that, forgot exactly buy there's some Reddit threads. I never bothered to check, myself.

surely I forgot something else
