Portal 2 crash on loading screen. Please help!
I bought Portal 2 on Christmas Eve, played through the first chapter and then a little bit into the second chapter. The game ran perfectly fine at a good speed. I closed the game, came back the next day, and the game crashed while loading the save game. A few days later, I tried co-op, but that crashed during the loading screen too. I looked up some similar problems on the steam forums.

I have tried adding
"setting.mat_tonemapping_occlusion_use_stencil" "1"
to the video.txt file, which did not work. I have tried adding -dxlevel 80 to the launch properties, and that didn't work either.

My laptop runs 64-bit Windows 7. If anyone needs me to be more specific, I will be. Please let me know if you think you know what can help, because I would really like to play this game again.

I have the exact same issue. When I'm switching levels, the game tends to freeze on the loading screen. No error message or anything. Sometimes it works, sometimes it doesn't.
It seems to me that the more time I spend in a given level, the higher the chance of a freeze is.
Can anyone help me/us?

just a stupid question: have you tried verifying the local files integrity?

Yes, as a matter of fact I have. I do it after every crash. Fixes the problem for a few levels (approx. 15-30 minutes, during which the game works fine), but not permanently...

I have tried everything I could get my hand on on the net, to no avail.

Any other advice?
