I’m experiencing a lot of crashing and lock ups on Xbox One X - Project Scorpio Ed. I even changed to Performance visuals and it still crashes quite frequently. Most times it happens during boss fights, but also happens when just running around killing normal bad guys. Other times it does a lot of stuttering, Mini-freezes which pause for a few seconds then resumes. Most times I notice this is when mobs are spawning into the game, via doors and entering into battle.
The only way to “fix” my issue has been to do a complete power cycle of the console which gets it working again and running smooth for a little while, but eventually the freezes and/or crash occurs again. It has happened with all 3 of my characters so far, so it’s not limited to just 1. I’ve never had this kind of performance issue with any other game playing at 4k graphics.
