I am running SW 2008 Vista x32 on a W7 x64 machine, so should I be using the ATI x32 or x64 drivers? I tried soft modding using the 8.723 x64 W7 driver, but my specviewperf scores are very low and I do not have the realview option in sw, so I do not think the softmod I did is working. It does show up as a v8700 in device manager. Thanks, Doug
