Well, seems like an updated driver did nothing to fix this... (or, whatever the latest driver was for my card, that I installed. Bah, I hate old equipment...)
Anyone got any ideas?
For those who are unclear what's this screen lag I'm talking about: it's like when you press PrintScreen. The screen stutters for a second before resuming. That's the same thing I'm experiencing whenever I activate afterburners, or fire a large group of weapons.
The game is loading something from your hard drive, I think. Maybe more RAM? If available? Or to reduce the distance drawn when activating mod? Less quality in game graphics? Maybe manually drop some processes before starting the game to free more RAM?
My RAM is 512mb, so I don't think it's lacking at all. Drawing distance has nothing to do with it, since I even tried it in single-player, and still the same thing. This doesn't happen when I turn off sound.
Even lowered my graphics settings to 800x600 16bit, and nothing's changed.
EDIT: Seems it might by my installation. I muted all sound from my desktop, and turned up the sound in the game, and the sound is not playing, but the lag is still there.
