--- Comment #141 from Night Nord NightNord@gmail.com 2011-05-17 10:47:40 CDT --- Guys, please, I'm sure that a plenty of active wine developers own some Portal 2 copies or there is just enough info for investigation start already. Please, let's let this bug a rest for a while, until someone will explicitly ask for specific info.
If you really-really want to help, try to debug this issue by yourself, maybe by testing in different environments, setup cases or different wine versions and if you will somehow manage to get Portal 2 running (that is - without cracks) (there is some rumors of working Portal 2 on wine without cracks, but nothing is proved) - post it here. If not - I guess that's just enough of "This doesn't work" posts and logs, so do NOT post it here.
Thanks.
