Quake 4
Unless you're running a timedemo, which lacks audio, Quake 4 frame rates are capped at 60 frames per second. We used the game's playnetdemo function to play back a pre-recorded demo at normal speed while using FRAPS to monitor frame rates. Those FRAPS results allowed us to calculate average and median low frame rates. We've also presented a graph showing frame rates across the duration of the demo.

Unfortunately, all our fancy frame grabbing is for naught in Quake 4. The 60 frames per second cap rears its ugly head, even on the Athlon 64 X2 3800+. This is how users will experience the game, though.

F.E.A.R.
F.E.A.R. has a handy in-game performance test that uses audio and spits out average and low frame rates. We took the mean of those averages and the median of the low scores.

The Inferno and X-Meridian lag behind a little here, turning in lower average and median low frame rates than either the X-Fi of the ADI 1988A. We're not entirely surprised that the Oxygen-based cards can't keep up with the X-Fi's hardware acceleration, but we didn't expect the ADI 1988A to fare so well. Sensaura rocks, apparently.
