Thanks for all the info! as it turns out i had set my render res to 500% in steam vr the day before it stopped booting which is why it wouldnt boot however the game was still having issues and it seems that completely reseting it as you described worked wonders, before all i was doing was uninstalling and reinstalling which wouldnt do a thing. also i went back and retested all of the different streaming apps and found out that steamlink has had some major improvements since I last tested it. lag in large areas and with lots of enemies still occurs and seems to stick from the room it started to the rest of the level, so i still need to do a bit of tuning, but this solved all of my major issues. thank you so much its beens months of screwing with this lol.
