Widescreen Gaming Forum

Half Life 2 Episode 2 performs exactly like the original and the first episode, means flawless widescreen support.

Same goes for Portal, a small puzzle game that's included in the "The Orange Box", with HL2E2 and Team Fortress 2.
The Portal is a HL2 Engine game, which means of course, flawless WS support.

SOLUTION:
Like other Source games, you can FORCE a resolution with command line switches under launch properties.

-w 3840 -h 1024

game runs properly, with only stretching of BG images.

Picts or it didn't happen.
