Prey has been in the making for 10 years (or more ?) and bring us portal gameplay pleasure. It?s powered by the Doom 3 graphics engine, but adds a lot of graphical enhancements to really tax the latest hardware in some of the more action packed scenes in the game. The demo of Prey allows you to play through some of the first levels, we tested the performance starting from when our hero runs through his first portal and finishing that current level.
Using FRAPS to track frame rate we hit the in-game 60 FPS limit easily in the lower resolutions, but once details are increased these high end cards show their muscle.
At 1280x1024 these high end cards have no trouble keeping frames high up; the 7950GX2 is slightly trailing the ATI cards, enabling anti aliasing seems to hurt performance more for NVIDIA in this game. The difference between the X1900XT and X1950XTX is none-existent.
ATI is dominating here, we redid the tests on the 7950GX2 several times here, but the outcome remained the same. When enabling 4xAA/16xAF at 1600x1200 the NVIDIA card drops below 30fps min. fps, but average frame rate is still well within playable region.
The ATI cards can hardly be separated, only at the highest detail levels we see the X1950XTX able to pull ahead.
On to the next game, FEAR. >>>>
