Far Cry is a classic FPS that most people still use to this day to benchmark their systems. It has introduced many graphical technologies to the world such as High Dynamic Range lighting.
Far Cry - No HDR vs HDR
The following results are from pure gameplay and not an official benchmark.
Far Cry Demo Performance - 4x Antialiasing
With all options, AA and AF cranked up, both graphics cards deliver the performanace for Far Cry. The GeForce 7600 GT still holds its own when at a higher resolution, but the NX8600GT TT outperforms by 8 frames per second without the Twin Turbo feature and 12 frames per second with it. The Twin Turbo advantage gives the NX8600GT TT a small boost.
DOOM 3 DEMO
Doom 3 was the most highly anticipated PC game when released back in 2004. It brought a new technology to NVIDIA's GeForce 6 and 7 Series GPUs called Ultra Shadow II, which accelerated a game's lighting and shadow calculations by first defining depth bounds in a scene.
Video Quality = Ultra
High Quality Special Effects = Yes
Enable Shadows = Yes
Enable Specular = Yes
Enable Bump Maps = Yes
Vertical Sync = No
Let's see how the NX8600GT TT does in OpenGL. Notice that the following results are from pure gameplay. Results begin with 8x AA enabled as the frame rate remained at a constant 60fps at all resolutions with 4x AA enabled!
Doom 3 Demo Performance - 8x Antialiasing
Doom 3 runs exceptionally well with the NX8600GT TT, but the GeForce 7600 GT still holds it own, especially when getting into higher resolutions. At 1600x1200 and 1280x1024, both the GeForce 7600 GT and NX8600GT TT tie in average frame rates! But Twin Turbo gives the NX8600GT TT a little extra push to come out ahead.
Doom 3 Demo Performance - 16x Antialiasing
At 1600x1200 and 1280x1024, both cards really don't perform that well. Even at 1024x768, Doom 3 is right at the bar of playable (25-30fps). Honestly, sticking with 8x AA not only gives you similar visual quality, but increases performance - especially at higher resolutions.
