Sluggish mouse movement

[Spude]

First of all I play this game on craptop, all settings, low 1368x768 res. I can tolerate bad graphics just fine but there is one thing that bugs me to no end.
My mouse movement is really sluggish I can not describe other way than: imagine a fridge magnet with little string on it and then on that fridge door try to accurately move the magnet around by pulling from string. It seriously hinders my already pisspoor improvement in this game.
In other games I play like TF2, L4D2, Painkiller my mouse works perfectly, smooth and responsive with no problems.

Any help for this problem? Does fps affect on mouse somehow?
Any help would be appreciated.

Yes, of course fps affects mouse movement.

Even in the menu I had the same problem.......then I bought a new graphics card

The mouse movement in other games isn't as heavily affected because not many games have a free aim mode. So because of that you have to add extra movement/increase sensitivity to get to the levels you were at in games without free aim.

Ok thanks you all. Decided to drop all settings to low and resolution lower and now it runs on tolerable 45 fps.
Luckily I´m gonna get new computer soon so I can enjoy this fine game.
