Quake 4 Official websiteQuake 4 was released in 2006, based on the popular Doom 3 engine from ID Software. Unlike Quake 3 this game also has a fully fledged single player story which continues the events from Quake 2.
In Quake 4 you, Matthew Kane, find yourself in a war with some kind of aliens called "Strogg". As a member of the Elite Rhino Squad u get dropped at the heart of the Strogg war machine. The scene we went true is at the beginning of Quake 4, when you walk outside for the first time, the “you are but a soldier in a war” approach also seen in the first Call of Duty, although the outdoor scenes are smaller in size.
The Air Defense Trenches level sure was a good place to benchmark Quake 4 as you get to see some indoor and outdoor action.
Both NVIDIA and XFX 7600GT offer very fluent gameplay. Most of the time the cards will be able to stay close to the engine's in-game maximum framerate, which is a comfortable 60fps. 4xAA pushes these cards a bit more, though XFX shows us that its higher clocks put them 5 whole frames per second in front of NVIDIA's reference design.
This advantage in FPS is most noticeable when there is heavy action on screen, while the min. fps with the reference 7600GT is still an acceptable ~35, the 5 fps extra on the XFX edition made a difference.
Increasing the resolution had the same impact as going from 2xAA -> 4xAA on the lower resolution, at 2xAA performance is now identical to 4xAA at 1024x768, with the same drawbacks and advantages.
Further increasing AA made the game unplayable as the min FPS was below 30 FPS resulting into a stuttering/choppy gameplay experience.
