my ati catalylst driver offered me to update today so I did.

after the update , my hashrate went down by almost 60Mh/s! im using a sapphire radeon 6950 flex 2gb with the -v and -w 128 flags in GUIminer under wind7.

before the update i had around 310Mh/s, not its only 240Mh/s - and all that changed is the driver version. besides that there were only a few windows update installed, but that all that has changed since yesterday when i still hab 310mhs

im using deepbit for pool mining.
anyone else having this issue?
any idea what I can do to get my lost Mh/s back?
