Based on reports at official forum, some of us are having this issues where game freezing (nvidia cards) or totally shutdown (amd cards) when playing the game?
Current workaround for me is to disable the boost clock (1411 Mhz) for my RX 580 and run the game with default clock (1250 Mhz). Luckily my GPU have this bios switch which I can easily do, though I need to ooen the side panel to do it.
Some people need to manually downclock their GPU or lower the voltage. Seems to happened with those factory OC type GPU.
CA has acknowledge this and hope there's some sort of fix. Might it be some power draw issue with the game?
