Portal 2 - Failure to Launch
Just to let anyone else who comes across this have my fix. There is a problem which has been much talked about on these and other boards where Portal 2 doesn't launch properly. In this problem Steam tells you it is 'Launching Portal 2' the screen goes black and then you get back to the Steam desktop without the game starting.

I have tried every solution I could find including -autoconfig in 'Set Launch Options', reinstalling ATI drivers, disabling the AMD External Events Utility and following who knows how many other tweaks. This worked for me, annoyingly simply:

- Right click on Portal 2 in the Games Library
- Select 'Properties'
- Select 'Set Launch Options'
- Type the following: -w <your monitor resolution width> -h <your monitor resolution height>
=== eg. on my computer I typed -w 1366 -h 788
You can find your resolution through the Control Panel in Windows (you really should know that, I guess :p )
- Click 'OK'

If you try to launch Portal 2 after you've done this it worked fine for me.

Good luck if you came across this error, it nearly killed me.
