renderizer: thanks for the link.. one question though - which detonators have you tried it with? I've tried the 30.82's and 40.72's, and each time have not been able to find the nv4_mini.sys. When unzipping the driver setup files it seems to have screwed up the file extensions - any idea if this is a known bug and a workaround exists? **EDIT** never mind.. was being a little stupid. got it working fine with 30.82's, and it rocks Paint effects and the 3dpaint tool are now about 4 times faster, and deformations in a viewport are now a bit faster too. top stuff, and thank you nvidia for providing me with a 750XL for £120
