Nvidia has released the official Forceware 259.09 WHQL certified driver for Windows XP, Vista and 7. These drivers are a special release intended primarily for developers, providing support for OpenGL 4.1 and GLSL 4.10. Note that the new features of OpenGL 4.1 and GLSL 4.10 require a GeForce GTX 400 series or Quadro 4000, 5000, 6000, or 7000 series card in order to function. ATI has released the official Catalyst 10.7 graphics driver for the HD 2000 series and above. This WHQL certified driver has HydraVision enhancements for ATI Eyefinity, enhanced pulldown detection, support for rotated displays on CrossFireX configurations, and GPU acceleration for VLC player 1.1.1. The drivers also contain performance improvements, as well as a range of bug fixes. Update: ATI has also released a 10.7 Preview driver which is newer than the official 10.7 driver and provides support for OpenGL ES 2.0.
