The performance of today’s top-end graphics cards is often limited by the capabilities of the computer’s CPU in Quake 4. This is illustrated by the fact that the results of the e-GeForce 7900 GT CO SuperClocked are similar to those of the GeForce 7900 GTX despite the use of full-screen antialiasing. The same goes for the Radeon X1900 XT – Radeon X1800 XT pair which differ by no more than a few fps while their average speed is over 100fps.
Serious Sam 2
Serious Sam 2 needs 512 megabytes of graphics memory to run fast at the maximum graphics quality settings. This is why the increased frequencies do not practically affect the performance of the EVGA e-GeForce 7900 GT CO SuperClocked which, like the ordinary GeForce 7900 GT, loses to the Radeon X1900 XT/X1800 XT and cannot provide a minimum of comfort even in 1024x768 when full-screen antialiasing is in use. It should be noted, however, that the ATI solutions are also rather slow in this game due to its wide use of shaders with multiple texture lookups.
