Copy this text to your clipboard. Go to your Steam games library, right-click Team Fortress 2, click "Properties", click "Set launch options...", clear any existing options and paste the new ones. If you do not do this, the game will have visual glitches and might be prone to crashing. Also, these launch options have to be removed when uninstalling the scripts.
