Just today i bought myself a Sapphire nitro 4GB version of the 480 and i'm getting huge fps issues on WoW: Legion. The issue is 100% the graphics card, as i was having better FPS with an R9 270x, which makes no sense.
my specs are:
Windows 10 64-bit
CPU: Intel I5 4460 @3.20 ghz
GPU: RX 480 Nitro 4GB OC
4 Gb ram
Crimson driver version 16.8.3 (recommended from the amd app)
Rolling back to older driver versions.
Fully reinstalling the drivers using DDU.
Any help is appreciated.
Edit: I just noticed my GPU is running at half the GHZ, so that might be it. Can someone help me?
Edit 2: Added a dxdiag
