The first one did a really good job of having an interesting range of guns and abilities which were very well balanced. There was no ‘best gear’. I’m sure they’re able to have things worth buying that don’t give you an unfair advantage over people who haven’t. It’s a morally hazardous area though.
The processor in 3 is a pretty sizeable improvement over 2. A quick and dirty a/b test I did found frames rendered in 13ms on q2 would render in 9-10ms on q3, so that’s a good 20 - 30% faster, even though it’s rendering a lot more pixels.
I think the important bit for meta though is making sure their range of headsets all have decent passthrough. No one is going to develop MR apps, and it’ll never take off, unless the whole user base can use them.
Personally I’d take the better lenses and resolution of the q3 over better passthrough though.
