This needs to be reintroduced in a sensible way, as well as rewritten:
== Alt-tab == On Windows, Source games are notorious for their poor alt-tab. All Valve Source games, except ''Half-Life 2: Lost Coast'' feature the -noborder launch option. To be able to seamlessly alt-tab, add: -window -noborder to the game's launch options. In Steam, you can do this by right-clicking the game, clicking properties and adding them to the launch options textbox. This does not work for '''every''' Source game; only those released as part of or after The Orange Box. Both [[Portal]] and [[Half-Life 2]] have been updated to include this functionality. Some non-Valve games, such as [[Zeno Clash]] support it, too. This will, however, result in a decrease in performance. == Console Commands == [http://developer.valvesoftware.com/wiki/Console_Command_List Source Engine console commands] will run on most Source games such as [[Portal 2]], [[Portal]], [[Garry's Mod]], and [[Half-Life 2]]. It should also be noted that every game will have its own commands in addition to these default commands and these can also be extend at run time, such as by mods. == Multiplayer == If you instantly get a 'Cannot connct to server' error when trying to connect to a server on áll source based multiplayer games and setting ports, disabling firewalls etc. don't work a router '''reset to factory settings''' may solve this problem. This problem seems to affect all source based multiplayer games at the same time, showing less servers when loading the server page and giving the error instantly when trying to connect. ==Engine Specific Errors== ===Failed to create 3D3 device=== When you encounter this error, teh game will fail to start and display this error. If you encounter this error, try the following steps to try and fix the problem: *Install the latest stable drivers for your Graphics Card. *Install or reinstall the .Net Framework included with your game. *Make sure you have installed all required and recommended Windows Updates available for your computer. *Attempt to start the game with to "-dxlevel 90" added to your launch options.
