Ever since i got my brand new rx480 wierd things have been happening. I tried re-installing the drivers but those keep occurring: When i turn up the AA in a game, i get weird artifacting which crashes the game. Also, every hour or so i get a black screen for like 1-2 seconds, this also happens when im not in game but more rarely. For example, skyrim runs fine with 8 samples of AA. But when i turn on FXAA, game starts artifacting and it crashes. For CSGO, it works fine with 2x MSAA, turn it up to 4x or more, and it does the same thing. Hell, even the radeon settings is artifacting sometimes, which is super wired. Help is appreciated!
Below is the artifacting, its the same in all the games.
