Performance in Simulators
Graphics cards from the Radeon X1000 family do not support vertex texturing, so they can’t use SM3.0 to render the water surface with the highest possible quality. Only Nvidia GeForce 7 cards can do that.
Pacific Fighters is a rather old title and it is also optimized for Nvidia’s graphics architecture. That’s why the GeForce 7600 GT looks brilliant here, making all resolutions through 1600x1200 playable in the “pure speed” mode and up to 1280x1024 at the “eye candy” settings.
The same-class Radeon X1800 GTO is slower in each resolution, and the Radeon X1900 GT in resolutions higher than 1280x1024. What’s curious, the gap is even bigger in the “eye candy” mode, although the memory bus load is higher in it. The Radeon X1800 XL is the only worthy rival to the Gigabyte GV-NX76T256D-RH thanks to its 16 TMUs.
The engine of X3: Reunion prefers the ATI Radeon X1000 architecture. The Gigabyte manages to reach the level of the Radeon X1800 GTO only at the overclocked frequencies. Different sectors of the game world vary in difficulty from the graphics card’s standpoint, so the results of the GV-NX76T256D-RH aren’t very high and suggest that you switch to 1024x768 resolution where there is a bigger reserve of speed. Full-screen antialiasing is not to be used on the GeForce 7600 GT, at least in 1280x1024.
