Because it's clearly an issue with the launcher, given a patched .exe works just fine (when I say fine, it bypasses the launcher and the game loads)
Why would a game be dependant on a specific BIOS version? Updating your BIOS to get a game working isn't, and should never be a legitimate fix for bad software.
Quite clear? It's a launcher problem.
Destiny 2 didn't work on AMD's new CPUs until bios patch. Does that mean Blizzard are a joke?
Aside from that, graphics wise, my rig can play at 4K at playable framerate without any image quality desegregation that is noticeable compared to native 4K and all whacked up settings.
No req to upgrade yet (just) - apart from keeping ahead of console curve.
