That's always been the problem for me with ATI they just can't get the basics right, refresh rates, black screens, shockingly bad control panel.
They have been in this industry for over a decade and they still have no clue.
When i had my 5830 in COH each driver would screw up the game in a different way usually the fire fx in the map, some drivers would just crawl the fps. I gave up. Had to make custom resolution or refresh rate profiles for basic setups. ..
I am not surprised to sre nothing had changed.
144 gaming has been out a while, why would you need to wait till Monday to hope it's been fixed?
I game at 60hz with a single you which is fine for me and as a result have never come across any major issues. Perhaps that's why I never see why people think nvidia is better. I had a gtx 670 not so long ago when I was into fsx and it was the same experience for me. Wanted to try out mantle so I went to the card I have now and needed more than 2gb ram as at the time I was on 2560x1600.
Now I will wait until June and hope amd price their cards well, as I dont want to give nvidia my money so soon after what they pulled with the 970.
