The NVIDIA Website now offers new beta version 304.48 GeForce reference drivers, the first beta from the R304 family. These offer various enhancements and fixes as well as the promise of performance improvements, saying: "Increases performance for GeForce 400/500/600 Series GPUs in several PC games vs. GeForce 301.42 WHQL-certified drivers. Results will vary depending on your GPU and system configuration." There do not seem to be XP drivers, but they offer drivers for Windows 7 and Windows Vista 32-bit and Windows 7 and Windows Vista 64-bit. Thanks Charles.
