Performance Comparisons with Prey

Originally announced in 1995, Prey has been a long time in the making. A series of technical issues put prey on the back burner in 1999, only to be revived by 3D Realms and Human Head studios in 2001. Being a unique title with it's 'Portal Technology', Prey allows players to warp to different areas of a level through the use of Portals, without a drop in framerates. Prey is also known for its extensive use of in-game gravity tricks, allowing the player to walk up walls and perform other unique moves. Prey is the latest game to use id software's Doom 3 engine, which is based on the OpenGL programming language.

As with Quake 4, Prey is an OpenGL title based on the Doom 3 engine. While the GeForce 6600 GT quickly claims the lead without AA or AF being used, the X1600 XT starts to shine once the graphics are turned up. The X1600 XT seems to handle higher resolutions and AA/AF better due to its increased memory bandwidth over the 6600 GT.

As we mentioned, the increased memory bandwidth really helps the X1600 XT shine. The 6600 GT's lead over the X1600 XT starts to fade with no extra pixel processong, and once we turn up the AA and AF, the X1600 XT manages to squeeze ahead by 1FPS. If you're planning on playing a lot of Doom 3 engine based titles, and are shopping for a mid-range card, we'd still have to recommend Nvidia because of its superior OpenGL performance.
