NOTE: SOME COMMANDS ARE NOT LEAGUE LEGAL - READ BELOW TO FIND OUT WHAT IS AND ISNT LEGAL.

 

Adding these to your CS link or in Steam (my games > right click on CS > Properties)
-console (add console)
-nojoy (remove joystick support, gives more ram)
-noipx (removing LAN options, gives more ram)
-noforcemparms -noforcemaccel -noforcemspd (disable mouse acceleration)
-dev (removing 100fps limit *STEAM ONLY*)
-heapsize (gives CS memory, set it by kbytes, example; i have 384mb of ram so i used:
-heapsize 300000 (it tells cs to use 300mb of ram as cache for CS) , set it to 60-80% of your total ram, help's alot in 1.6)

Sensitivity:

CS is not Quake or UT, you dont need high sensitivity, you dont have rockets and plasma rifles, also CS has a great sound engine so you dont need to make some "FAST" moves. Getting used to low sensitivity will improve your aiming, lower your sensitivity by 0.5 every week, and you may see improvements, it also depents on your mouse and options, personally im using 2.5 because i have ie. Lower sensitivity is better, so get used to it.

Config commands:

disable voicecomm (we got team-speak, ventrilo, why hear these 10 year old kids yelling?)
