Wolfenstein: Enemy Territory
While we are waiting for the game "Call of Duty", which uses a very advanced version of the good old Quake3 OpenGL 3D-Engine, we chose Wolfenstein: Enemy Territory as a representative for games based on this engine. The game is a free standalone multiplayer game that does not require the original Return to Castle Wolfenstein to play it.
We used the build in benchmark procedures and tested with a replay recorded during a clanwar session we found on the web.
The game Wolfenstein is clearly owned by NVIDIA's FX cards.
