Why when i jump, shoot, etc. i hear the sound about a half second later? Is it a game bug or i've got something wrong?

if you are running the nexuiz-sdl version try running the normal one. I have this roblem when running th .sdl. Also if you are running the normal version, try the SDL version.

If neither helps, try adding -sndstereo and/or -sndspeed 48000 to your start-up command.
