Performance in First Person 3D Shooters

Doom 3

The Leadtek kit performs on the same level as the GeForce 6800 GT in this game and is a little slower than the GeForce 6800 Ultra. Note that there’s almost a zero effect from overclocking – a speed gain of 1-2fps is really negligible.

It’s different when we enable such picture-enhancing options as full-screen anti-aliasing and anisotropic filtering. The combined amount of graphics memory of the WinFast PX6600 GT TDH kit is only 128MB and it cannot rival the GeForce 6800 GT that has 256 megabytes of memory on board. Even though the Leadtek solution delivers the performance of an ATI RADEON X850 XT Platinum Edition, we can’t call this a good result since ATI’s cards are generally slower in Doom 3 than their NVIDIA counterparts due to the specifics of the game engine and ATI’s less efficient OpenGL driver. Moreover, a speed of 25-30fps isn’t enough for comfortable play.

The Leadtek kit even outperforms the GeForce 6800 Ultra on the d3dm4 map, probably because this multiplayer map is simpler, having no game characters. Overclocking is unrewarding, again.

Having a small amount of memory and two 128-bit buses instead of a single 256-bit one, the WinFast PX6600 GT TDH SLI is ahead of the GeForce 6800 GT in the lowest resolution only. In higher resolutions it slows down and is just about 10% faster than the RADEON X800 XL in 1600x1200.
