The following benchmark results are with antialiasing enabled. With the exception of Warhammer, at all resolutions, and The Witcher, at 2560x1600, 4x multisampling antialiasing was used. In Unreal Tournament 3, antialiasing was forced via the driver control panel.
Neverwinter Nights 2
With 4x antialiasing, the performance of GeForce GTX 280 over the MSI N260GTX OC across all resolutions increased to 9.1%. Factors that contributed to the increase include the greater number of stream processors available on the GeForce GTX 280 as well as a greater amount of framebuffer memory and memory bandwidth.
