Portal 1 edge issue
I've been noticing some graphical issue with my Portal game. Every time I see other screenshots or videos, the edges of each red/blue portal have a "fire" outline.


Mine just look like a gradiant. What is wrong?

Looks like directx8 portals and lighting. Common issue since some random patch forced everyone's client to default back to directx8. Try adding "-dxlevel 90" or "+mat_level 92" to your launch options to force it back to directx9. Just remember to take it out after launching it once or else your in-game video options will keep resetting.

Hope it helps.

Just to be clear:

I use those commands in the Launch Options
Run the game
Reset my settings to the ones I had, because they were erased
Quit the game
And remove the Launch Options

Pretty much yes. It'll force the game back into directx9 and hopefully when you remove the command from the launch options it'll stay in dx9.

Alright, I'll give it a go next time I'm on!

It worked perfectly! Thank you!

Does Half Life 2 need this as well?
