I've just bought my new r9 380 gpu, everything seems to work fine without any issue except that sometimes when I play Assassin's Creed Unity the gpu stops working and it stops giving display, sometimes it the game simply crashes showing the driver has stopped working and has recovered successfully, I get this issue in this game only, all the other applications, softwares and games runs absolutely fine.
I tried updating the driver, from 15.5 beta to this latest crimson 15.11.1 beta, tried verifying game files, lowering the settings but these doesn't seems to solve this only issue,
but it's a random problem, sometimes it happens sometimes it doesn't.
I also get mantle api crash error when playing battlefield hardline, it runs fine with dx11 api though, I haven't played any other mantle game yet so can't be sure if this is related to the api or the game.
Please can someone explain what this issue is about? and how to fix it?
