Hi guys

Did someone with ATI HD6950 has improvement with new beta 14.6 drivers?
I allready instaled it, but without any change in hashrate. I Remove old .bin files, but nothing changes.
Windows 7, HD6950 2GB
Any clues?
I have the feeling that the new driver gives improved hashrates only for 270, 280 and 290 cards. My 5870, 5790, 6950s don't show any improvements...
