Testbed

Games are tested on Pentium 4 3.4 GHz (800 MHz FSB) PC with ASUS P4C800-E (i875P) motherboard and 1024 MB PC3200 3200.

The test is run only under Windows XP Service Pack 2 and DirectX 9c.

The following cards were used in making of this material:

  • ATI RADEON 9200
  • ATI Radeon 9600
  • ATI Radeon 9800 Pro
  • ATI Radeon X800 Pro
  • NVIDIA GeForce4 Ti4600
  • NVIDIA GeForce FX 5200
  • NVIDIA GeForce FX 5700 Ultra
  • NVIDIA GeForce FX 5900
  • NVIDIA GeForce 6800 Ultra

The latest changes are marked light-red.

Games are tested with the latest reference drivers (66.93 for NVIDIA GPUs, 4.11 for ATI GPUs) coupled with the latest patches. When a bug is found, it's tested on the next reference betas. Exceptions prove the rule :-)

Some bugs may occur in our testbed only. So if you don't witness them, or witness bugs previously unwitnessed :), please email us providing most details about your PC configuration (processor, chipset, graphics card and drivers, OS, DirectX version, game version). Besides, you can send us a screenshot.
