Quake 4 is built upon the Doom 3 engine, so it wasn't hard to figure out how to record a demo and create a batch file for this game. We recorded some time towards the beginning of the game... I'm not sure precisely where it was recorded because I can't stand this game and I didn't pay attention to what level I was on. The demo represents what I deemed to be average gameplay after playing the game for a couple of (dreadful) hours. As usual, each test was run three times and the results averaged.

The sweet spot in Quake 4 looks to be 1024x768 with 4xAA/8xAF with the X1800 GTO, since going to 1600x1200 with AA/AF enabled will cause some laggy performance. The 7800 GT maintains a healthy lead in most of the tests. In all cases, the X1800 GTO performs well ahead of the X1600 XT, although that extra performance comes in the form of a $100 price premium. The X1800 XT stays in the lead the whole time, with a big gap at 1600x1200 with 4xAA/8xAF.
