This is a preview level of the Outer Base from Quake 2 which is a part of the new Quake 2 Remix Mod for DOOM 3 I have in the works. Mostly everything has been remade from scratch to give a new Quake 2 experience within the DOOM 3 engine. It is also a work inprogress still. It has been tested on several Nvidia graphics cards including GeForce 6800 Ultra, GeForce FX 5200 and GeForce 4600 TI. You get ultimate performance in this level using the recommended card for DOOM 3 which is the GeForce 6800 series of cards. Using the othertwo cards the level played ok, but the FPS was very low in certain areas. There have not been any test's with ATI cards, or any other cards. If you run into any issues, please let me know.
