Edit: Just found a record demo feature, the commands are: demorecord, demostop and demoplay. When i write demorecord in the console it responds "Recording demos/demo00001.demo" but when i write demostop it doesen't say anything. When i write "demoplay demos/demo00001.demo" the game starts the loading screen of the particular area I recorded the demo in and then the game crashes. I suspect that I'm not using "demostop" correctly since the console doesen't respond anything and the .demo files end up 1kb. Anyone with knowledge about these stuff? Guess it's similar in quake 4, which i never got into.
