avada - If I'm not mistaken I think the aiming issue in GTA3/VC is a problem within the game it's self at higher resolutions. I've found running it in a 4:3 resolution solves the issue. I think there are POV mods to solve it.
Now that you mention it there was the issue that the aim wasn't where the crosshair was. But there was also the issue with mouse movements too.
