ATI has managed to do a lot better than NVIDIA when it comes to the drivers for Windows Vista and with its latest update it also fixed a decent OpenGl support, something Microsoft has been criticized for excluding from Vista initially. Anyway, DriverHeaven has tested ATI’s drivers for Windows Vista and compared these to Windows XP’s equivalent. It turns out that ATI has done a great job with its drivers and when it comes to new games with dual-core support and high memory requirements Vista performs better than Windows XP.
