This game is awesome, but I've got a gripe on the PC..
Is it just me, or does anyone notice a HUGE performance hit when there's extensive (or even just minor) collision detections nearby? I used to think it was just the shotgun, because every time I got into a firefight against people with the shotgun, I'd drop to 0 fps for like 2 minutes while it sits there and finally finishes the shotgun fire. I then found a 'fix' for that, and it helped slightly, but now that I'm further into the game, I notice that it happens whenever two things hit each other (excluding enemies/npc). So, if I crash my vehicle into some douchebag's vehicle cause he won't move out of my way, I have to wait, literally, 2-4 minutes for it to finish 'catching up' from the lag, meanwhile enemies can still fire on me just fine, and I usually find myself dead before the lag is finished. Other than that, I can run the game fine at 30+ fps with max graphics and 4x AA.
