Left 4 Dead

Left 4 Dead – DX9

Notes

GeForce GTX 275 performance in Windows XP x64 continues to suffer in Left 4 Dead. The card ran 2-5% slower under x64 depending on the resolution. Vista performance was also down in comparison to XP at 1600x1200. Once again SLI performance was actually better under Vista and Windows 7; the SLI setup was up to 2% faster under Windows 7 when compared to WinXP.

The Radeon 4890 performed pretty evenly regardless of OS tested, although again, CrossFire scaling benefited ever so slightly under Windows 7 compared to WinXP at 1600x1200. The CrossFire config ran 2% faster in Windows 7 when compared to XP.
