I got this installed in Vista x64 with a GTX 260-216 @725/1450/1200. A couple of observations
- Fallout 3 started stuttering for a couple of split seconds, no crashes but annoying
- Rivatuner 2.24 works normally regarding overclocking and fan settings, just used ForceDriverVersion setting
- Crysis performance dropped 1-2fps from ~47 at 1680x1050, all-high, noAA
- Physx was disabled by default in the NVIDIA Control Panel after installation, enabled it.
- Nothing else different
Recommendation: I wish I had waited for the next 19x driver since Fallout 3 is the only game I play.
