It could have just been Reflex, I'd need to go hijack his rig to double check!

I don't have any 5000 cards at hand currently either, although might soon and will look into it more.
HL2 does a serious number on me for some reason, but I do suspect it's something most don't deal with. I have a highly dominant right eye, my brain sort of compensates for that with the left when both are open, but if I close said dominant eye the left is a blurry mess and it's not something that glasses can fix. It could be that my circumstances are making the way MFG looks worse, it's not something that most people need to deal with. It makes VR a nightmare for me too funnily enough, as much as I'd love to dabble with it.
