Its the same story with Quake 4. While there are more transparent textures throughout the game than F.E.A.R, the Data Processing Terminal level doesn't have any - at least from what we can tell. If there were any transparent textures, the frame rates at 1024 x 768 is still high enough to allow very fluid, playable frame rates, although 1280 x 1024 may prove to be too much.

As expected, there are only slight variations between the three transparency antialiasing settings. There is something odd near the end of the level though, both the GeForce 7800GTX and 7800GT seems to drop quite significantly in default settings to AA performance levels. Looks like that's when the elevator hits the bottom, but even then performance is still above 60 fps on both cards at 1024 x 768 at that point.
