hey guys im new to cs:s but not to fps games on the PC. i downloaded cs:s yesterday and i noticed that my keyboard and mouse dont always respond to my movements. i dont know what the problem is because there is nothing in the options menu other then the option to smooth out mouse movement and that does not help at all. also the computer is brandnew and BF2 runs perfect on it. i just need some help and some tips maybe... thx

Sounds like you might need to find a lower ping server.

are you possibly using a wireless mouse and keyboard that could possibly cause some delay.
also agree try to find a lower ping server.
