Dungeon Siege
Dungeon Siege is an RPG based on a T&L compatible DirectX 7 engine.
Dungeon Siege's 3D engine has an automatic detection routine to determine the video card in use and then set the detail levels accordingly. If a card is not recognized, the engine defaults to the most basic low-quality settings. ATi supplied us with an updated configuration file for the game, which adds the Radeon 9000 and Radeon 9700 to the list of supported cards. NVIDIA's GeForce4 was already supported. Of course, both cards use different default settings, but when the GeForce4's settings were changed to match those of the Radeon, it resulted in slightly lower performance, so we decided to let each card run with its own default setting and call it fair.
The results are nothing short of amazing! While the performance of the GeForce4 drops with increasing resolution, the Radeon 9700 is able maintain the same high level of performance in all resolutions.
