I haven't finished the game as I'm only 18 hours in, but I had to stop due to almost having my head explode from motion sickness. This hasn't happened in any other game to date. Granted, I'm playing on my Xbox One X, but that shouldn't really matter.
Supposedly 7 years ago the game was originally going to be dev'd for the PC, PS and Xbox consoles (not next gen). There have been some great game moments but overall the glitches, the lag and the almost constant screen freezing (especially after the last 2 patches have led me back to Valhalla for the time being. I'll wait until the Jan/Feb updates are released, or, I upgrade to the Series X.
This will go down as the worst game launch ever, even worse than Anthem or Fallout 76. In this case it's even worse and more egregious due to the hype train lead by CDPR in the years leading to launch. The norm should not be what was done with The Witcher and release crap to be fixed later, not after they've gotten everyone's $$. Sad CDPR, really, really sad.
