The game doesn't crash a lot anywhere else but whenever I go to the Himalayas the game hard crashes a few minutes into the zone. Sometimes I can alt tab out and kill the process but other times my computer locks up and I have to force a hard reboot.
Event viewer after rebooting shows this:
Display driver amdkmdap stopped responding and has successfully recovered.
