Our testing methods
Both the ATI and NVIDIA cards were left at their driver default settings for image quality, with the exception that we turned off vertical refresh sync on all cards.
Our test system was configured like so:
|Processor||Athlon 64 3800+ 2.4GHz|
|System bus||HT 16-bit/800MHz downstream|
HT 16-bit/800MHz upstream
|North bridge||K8T800 Pro|
|Chipset drivers||4-in-1 v.4.51|
|Memory size||1GB (2 DIMMs)|
|Memory type||Kingston HyperX DDR SDRAM at 400MHz|
|RAS to CAS delay||2|
|Hard drive||Seagate Barracuda V ATA/100 120GB|
|Graphics|| Radeon 9800 XT 256MB AGP|
Radeon X800 Pro 256MB AGP
Radeon X800 XT 256MB AGP
GeForce FX 5950 Ultra 256MB AGP
GeForce 6800 128MB AGP
GeForce 6800 GT 256MB AGP
GeForce 6800 Ultra 256MB AGP
GeForce 6800 Ultra "Overclocked" 256MB AGP
|OS||Microsoft Windows XP Professional|
|OS updates||Service Pack 2 RC2, DirectX 9.0c|
We used NVIDIA's ForceWare 61.77 drivers for all of the GeForce cards, and we used ATI's CATALYST 4.9 beta drivers, intended for DOOM 3, with all the Radeon cards.
The test systems' Windows desktop was set at 1152x864 in 32-bit color at an 85Hz screen refresh rate. Vertical refresh sync (vsync) was disabled for all tests.
