This is not really a guide but just some quick, but useful, console commands. I use these commands whenever I record a demo or need to take a screenshot or something like that, where I dont want the HUD to be displayed. Btw. the definition/meaning of HUD is ?Heads-Up Display. Write one of the following, or both, commands in the console:
[b]cl_drawhud 0[/b][default 1] This completely removes the HUD even the crosshair.
[b]cl_draw_only_deathnotices 1[/b][default 0] This removes the HUD, but will display the death notices in the corner of the screen as usual.
[b]Please note:[/b]If you want to hide the UI overlay/HUD in GOTV you can just use the above commands. If you want to use the commands in-game you have to enable ?[b]sv_cheats 1[/b] first. While you are here, you might find this command useful. If set to 1 (which is default), the clan name will appear next to the players name in the death notices:
