Performance in Simulators
The engine of this game being oriented at the GeForce 6/7 architecture, it’s no wonder the Gigabyte Radeon X1900 XTX is on the losing side. However, this graphics card is capable of giving you a playable frame rate in resolutions up to 1280x1024 with a min speed similar to that of the Gigabyte GeForce 7900 GTX. Unfortunately, the Radeon provides a worse-quality picture than the GeForce because the game requires support for vertex texturing, and Radeon X1000 series chips lack this capability.
The space simulator X3: Reunion favors graphics cards on ATI Technologies’ chips and the Gigabyte Radeon X1900 XTX gains a confident victory over the Nvidia G71-based solution. Both these cards provide a comfortable frame rate in 1600x1200 with enabled 4x FSAA, their speed never sinking below 40fps.
