MOUSE OR "GAME CAMERA" LAGGED AND BUGGED

[CulitoToFakeIt]

good night every one, my problem is the following; I installed advanced launcher so that the game had better performance but it happens that soon after I began to notice the mouse or "camera" with a lot of lagg when moving it, I don't know why, I eliminated the advanced launcher from my game but I still have this problem, none of this problem is related to FPS (or so I think), constantly the game is going to me at 35-60 fps (it depends on the area where I am) my cpu is an - Intel Dual Core e8500 3.16 Ghz - GPU- Nvidea GTX 750 2gb - 8gb ram ddr2. 

What do you recommend me to do? please i wait for answers thanks.
