Doom 3 v. Quake 4 Performance
In many respects, the Quake 4 game-play is incredibly similar to that of Doom 3; however, its frame-rate is evidently different. When performing the weakest of the strenuous benchmarks, 1024 x 768 - Low Quality, there was a mere 6.8 frame per second difference, but once we began enabling AA and AF, the results began to slide together. Whilst the settings were at 1280 x 1024 - High Quality - 8xS AA/8x AF, there was merely a 1.4 frame difference between the two games. Although no results can be decisively concluded due to the slight difference in testing demos, in general we've found Quake 4 to be more GPU demanding than CPU bound. More or less, the performance between Quake 4 and Doom 3 is similar but Quake 4 is using a tweaked/updated version of the Doom 3 engine and its technologies. Keep in mind, our testing of course was all under Linux, and the Windows version of Quake 4 is likely to share a different fate. It's also note worthy that upon the much-anticipated release of the NVIDIA Linux 1.0-8XXX (Rel80) drivers, these results are likely to change even more and at that time, we'll deliver some updated numbers.
