--- Comment #6 from Ronny Schmatzler schmatzler@googlemail.com --- The launcher only lists 4:3 resolutions.
But you can choose any resolution you want via the advanced options. There is an option to enter a custom launch command.
Just enter in there:
++screenwidth "1920" ++screenheight "1080" ++screendepth "32"
Now choose any 32bit resolution you want in the display tab and you get Full HD regardless of what you've chosen (you just have to select a 32bit resolution to get it to work with better textures).
