No idea, you need to ask AMDmy. 

Tested Omega driver in a few games, slight improvement in overall fps and some open world game "feel" much smoother, might be placebo but i know what i see and feel. Gonna try to reinstall GTA:ELC and see if it playable now with my quaddie.

The biggest improvement with this driver is on Assassin Creed: Unity, what used to run sub 30fps average for me now runs around 40-50 and sometime 60 with Ultra High Texture and Enviroment Quality + SSAO + High Shadow + FXAA. Previously overclocking in ACU only give 1 or 2 fps but now it scaled accordingly. I'm gonna try Arma 3 tomorrow and see if the GPU usage improved.

Base clock 850mhz 1250mhz | 44.5 Fps

Overclock 1150mhz 1500mhz | 56.8 Fps

On previous beta driver this same spot only give me 33fps@1050mhz


AMDMy, give this man two 290x.
Hopefully they will fully support the older GCN1.0 card, i wish it's not a "hardware limitation" problem. From what i've read in some forum, only the R9-285(latest GCN) support 4K VSR, the 290s only support up to 1800p and the resolution selections is very little.
