This set it's not good for me. I haven't tried BF4 yet, and I think I won't either. I ratter play with DX11 until something stable for my machine comes around. I have artifacts on Thief ("jumping" screen (I double checked my clocks, so, that's not the problem), although, this ONLY happens when I enable the exclusive fullscreen mode) and somewhat bad performance, and the cause seems to be the lack of exclusive fullscreen mode, since when I enable it, the game runs without a performance penalty but, I have the aforementioned bug. All of this does not happen with Cat 13.12 Another example of a game that does not work so good is Tomb Raider, I have lower performance than with Cat 13.12. Around 10~15 fps less from 60 to 50-45 fps depending on the scene, while with 13.12 is a loss of 5 fps in the same scenes So, all in all, I'll wait for something more stable, maybe I pass a couple more of betas before I return to it.
