hi people i have a problem that steam support did not solve : my portal 2 doesn't work on my pc, while the first works like a charm. i already uninstalled/reinstalled it twice, does nothing, what could it be ?

- right click on the game in steam library
- click set launch options
- type in -w <number> -h <number> where the numbers are you resolution width and height
=== for me it was '-w 1366 -h 788'
-click 'ok'

- try starting it up
