CS ProMod have the same bug, which is in CS 1.6, CSS also. For example, while shooting from usp bullets should creating a straight line(look this demo http://www.speedyshare.com/files/25650962/qwe.dem - pov CS 1.6). Bullets from deagle should go in the one point. Few have such a recoil, probably it depends of hardware. This is a bug in the game code.
