Left 4 Dead mouse delay problem

Hi crossfire,

I have a mouse problem that i am only getting in left 4 dead and no other games.

The problem is that when i move my mouse it takes the game around 0.5 seconds to react and move the xhair.

This makes it really hard to aim, u may think its not really that noticable @ 0.5 second delay but it really is.

I have got stable fps and ping so i really dont know how to sort this lag out.

I wasnt sure if its because of my razer drivers (i have razer deathadder) but its only in l4d that i have this problem.

i hope u can help.. thanks :))
