I can only speak about the quake 1/quakeworld source (I haven't studied the quake2 code enough yet), but it's actually nothing that complex. In fact, it's the opposit. quake doesn't do the integeration properly at all. It just adds the gravity acceleration to the velocity then the velocity to the location. I'm not sure if t squared shows up in the physics code or not (it looks like it does, but indirectly), but the 1/2 for the 1/2at**2 doesn't. Basicly, a projectile (player, grenade) has a piece-wise linear trajectory that doesn't touch the correct parabola except at the start point. Quake: the universe where G depends on how fast you can blink your eyes.
