Counter Strike 1.6 Mouse Laggy/Choppy non-steam?

I recently got a new monitor and It's pretty good.
So I started playing Black ops 2, High FPS all smooth and good.
Minecraft also smooth.
BUT
Counter strike 1.6, 100 FPS but the mouse when I move it, it feels like 40 FPS even though its 100, even with 352 FPS it feels like that, is there any solution to this?
I'm using Non-Steam CS 1.6 (WaRzOnE) Client v48 2009 update blah blah.
It seems to happen after I got a new monitor.
I really need help cause it's really hard to catch a good grip on the crosshair, I can't stay stable since it's choppy/laggy or whatever you might call it.
Note: Only in CS 1.6

Vsync is off (ATI CCC)
-steam -game cstrike -noipx -nojoy -noforcemparms -noforcemaccel are the launch options
and mouse filter is on.

Added (1). EDIT: No it's not my internet, 0 Chokes and Loss, happens also in single player.
And I repeat it happened after getting a new monitor.

Your internet connection may be slow- or there must be some kind of connection problem
