So I reinstalled my game yesterday...

I thought that reinstalling would make it run quicker. No mods = No lag was the theory. However, I went to play multiplayer with a friend and I got about 2 fps and ended up getting kicked from the server. The really confusing thing is that the game is running a lot slower than it did with mods on. I could get about 40-50 even 60 fps with loads and loads of mods, but a fresh install doesn't seem to want to perform.

I'm running the latest patch.

Can anyone help me out? I'm looking for some must-have tweaks for my game.

(I'm already using a commandline.txt)

Thanks.

Did you tried to use low settings?. Other thing, It'd help a lot If you post your PC specs.

Yeah if you could post your specs that would be good. Also make sure that you completely removed all other Gta files as this could be causing problems.
