Just got an RX 480 recently and while WoW is much nicer getting off Intel onboard, I was left dissapointed with my SL experience. Chances are this is driver related, but it's odd how it's only SL that's giving me a problem. Whenever I turn on advanced lighting model, there is this wierd line of wut going down my screen. While I can be content with advanced lighting model off, it kind of defeats the purpose of a graphical upgrade. Below is how it looks on my end with and without advanced lighting model on. (screenshot is of Firestorm, but other viewers give the same result): Anyone else encounter this issue that also has an AMD card or has an idea of a fix?
