Hi, I have a 8800 GTS 320MB, Vista x64 SP1 with UAC disabled and forceware 175.16 whql. I tried to enable hardware masked units in rivatuner 2.09, changing from 96 sps and 20 rops to 128 sps and 24 rops (see img), but the 3dmark06 score is the same after the changes (showing that the sps and rop aren't enabled). In my previous windows (xp 32bits SP2) the unlocking worked well. How can I make the unlock work in my Vista x64? []'s
