Have you updated your video drivers?

Yup :}}

 

Let's try turning V-Sync off.

You will need to open the Nvidia Control Panel and go to 3D Settings > Advanced.

Look for Vertical Sync and turn it off.

You may also have to disable V-Sync in your game options.

 

I turned if off in NVIDIA CONTROL PANEL but how can i turn it off in the game ?

 

Have a look where you would adjust the Video Options.

 

there is nothing that says something about vsync

 

Alright, try running the game now. Do you notice and mouse lag?

 

its still the same... ;[[[

 

In your game, open Console and type each of these:

fps_max 101

cl_dynamiccrosshair 0

cl_crosshair_size small

cl_cmdrate 101

cl_updaterate 101

rate 30000

See if that helped.

Also, is your mouse plugged in via USB or PS/2?

 

my mouse - USB

and those setting did not help !!!

 

Do you get a delay with the mouse on the menu, during gameplay or both?

You could try lowering the in-game resolution just to see if that eliminates the lag.

 

You use mouse fix?
Try reinstalling it!.
What is the brand of your mouse? Maybe someone will fix for this bug on the official site of the mouse
