This is not exactly documented all that well on the internet as far as runnable applications go. I tried this one out recently. It's a Quake 3 test version that was apparently created just for that effect, which cannot be turned on or off, at least not in the menu. The motion blur is seen on the weapons and powerups laying around. Also probably on moving characters, but I don't think you can spawn bots in Q3Test without replacing the exe, so couldn't check that out.
The effect is quite nice and subtle actually. Probably one of, if not the earliest use of such an effect in PC games. Such framebuffer effects were already widespread in N64 and PS2 games back then.
The problem with it is that it absolutely needs 4xFSAA to be displayed correctly. With no FSAA and 2xFSAA it's just varying degrees of screwup on those objects. Probably the main reason why they haven't bothered to patch this in the full version (besides, obviously, the demise of 3dfx), because I doubt people would have settled for ~17 FPS drops@800x600 on a fast game like this.
Apparently Serious Sam First/Second Encounter support this as well with these commands written in the console:
ogl_iTBuffereffect=2
ogl_iTBufferSamples=4 (8 for V5 6000)
It's supposed to only work with 16-bit color depth and bring faster FSAA than with other games, also depth of field (in the background)+motion blur (on the ejecting cartridges) effects. There is a video of that on youtube, but the author makes no mention of it, and you can't see very much to begin with. I don't have those games, so can't test it right now.
Also I have noticed that with 3DMark2000 it constantly keeps saying "TB" (regardless of card) in the settings line, so that could mean that it's used there as well.
Oh, and finally... I would have posted some screenshots of it here in Q3Test, but the screenshot function in the menu just refuses to work. 🙁 It says "wait; wait; wait; wait; screenshot" or something, but I can't find any screenshots in the folder or anywhere else afterwards. Binding it to a key and pressing that throws me out of the game. And printscreen just gives a mess.
