Is it frustrating to play FPS GAMES with controller and not mouse?

May be...

its impossible to correctly aim and fast. u agree?

any tips how to improve



like on BF bad coMPANY?

I think it's all in the control scheme. I have no problems with games like CoD4. Maybe you should think about researching and investing in the Frag F/X controller if you don't like the Dualshock/Sixaxis.

i disagree i play FPS games with game controllers and not a mouse alot and its not hard you just need practice=)
