An option to disable shadows and reflections would be nice, but devs don’t care for this.
I’m having same freezes, after using commandline sent by OP, i played two consecutive matches without crash.
I’m constantly forcing RAM clean because OW2 has an memory leak, and keeps all stuff from all previous matches loaded on memory. I hope devs fix this soon
UPDATE: I left game away from ~2 minutes while i was driking some water and freezed again, my luck is because i was in main menu.
