Prey is, without a doubt, the most fun I've had playing a game in a very long time. It's simple, the graphics are amazing, the use of gravity is wickedly awesome and the portals are a nice twist on the elevator or big cargo door so often used to signify the changing of levels. I was bummed out when the game ended, but I felt it ended well and the setup for a sequel left me wanting more.
I tested Prey with all the settings maxed at 1600x1200, 1280x1024 and 1024x768. Without giving away too many details of the game's plot, I tested in an area that was rife with Collectors, so combat was intense and constant. I played the same quicksave every time to get results as close to identical as possible.
Not surprisingly, the cards were running at the in-game maximum of 60 FPS at 1024x768. Higher resolutions are where the overclocked Inno3D GeForce 7900 GS really came into its own. The increased clock speed had a huge advantage over the additional 4 pixel-pipelines of the GeForce 7900 GT.
The 31% increase in average frame rate between the GeForce 7900 GS OC and GeForce 7900 GT at 1280x1024 made my jaw drop. I repeated the test three times with similar results every time. The 18% increase the GeForce 7900 GS OC had at 1600x1200 isn't that large of a percentage, but considering the graphical demands at settings that high, the increased performance is welcome.
