Hi Guys,
This is old problem with every p7811-fx i found a fix for it but i cant seems to follow the fix is to set "Force constant performance level" to performance 3d in riva tuner.So i downloaded riva tuner but what i found is its saying no supported drivers but after using power user in riva tuner i got it through now when try to set "Force constant performance level" to performance 3d then apply and ok it automatically gone back to disabled it asked me to restart i clicked ok but after restarting it was same "disabled" i again change it to "performance 3d" it agains asked me to restart but after restarting it was still disabled.
So can anyone here tell me what to do? or is there any other software which can do this thing?
