Feeling at the end of my rope here, I've done all the advised driver options up to and including DDU. I cahnged nothing else about the system but this card, it passes 3DMark stress tests no problem but when I play Horizon Zero Dawn or Outer Wilds it crashes after a while to desktop with a driver time out error. It has no performance issues otherwise, I just can't consistently play a game, sometimes it crashes almost immediately once I start playing the game, sometimes after half an hour or so.
I've installed latest chipset drivers, run a windows memory diagnostic test, tried upping virtual memory, am currently running 21.4.1
