We now turn our attention to DirectX 10 performance under Windows Vista. Although Windows XP remains a popular operating system for gaming, there are specific graphics features that are exclusive to Windows Vista.
Crysis
Crysis was the benchmark of choice for this series of tests. Please note that results are limited to the EVGA GeForce GTX 260 Core 216 Superclocked and do not include the GeForce GTX 280.
