Game definitely suffers quite badly from visual compression artefacts when using the Quest + Link but your mind definitely overlooks it unless it's almost completely pitch black. The graphics, though, are absolutely incredible and it's by far the best running VR game I've tried (outside of stuff like Beat Saber) despite it simultaneously being one of the best looking. Valve are masters at optimisation and polish, it seems.
As for the game itself... oh boy this is good. The level of interactivity on display is just incredible and it 100% has Valve's incredible level of pacing and level design.
I was up against an armoured headcrab and, instead of shooting it, I managed to incapacitate it with a box. That's something you could never do with just a flat screen, and it was amazing.
