Try lowering the resolution
Same troubles on lower resolution

did you try setting texture resolution to low, disable shadows ... ie, play with the lowest possible settings/resolution.
Yes, I tried to play with lowest settings. I don`t know what I can do with it, except waiting for new commits from nouveau developers :E
Water rendering issue is fixed in latest mesa master, fix is in Fedora 15
It's nice seeing the Open source drivers progress at a descent rate for a change. And glad that Amnesia has been helping getting it there.
Hi, I want to update on the open source driver situation (at least for r600 cards)
I have a 5850 card and I'm using the Mesa r600g drivers to play the Amnesia demo and it works very well with all settings to max and full hd resolution.
I'm looking forward to buying the game if the demo finishes without problems
(of course I'm using the latest git)
Now i see this. My brother has Windows XP, and in every custom story + Main story his screen turns upside down. :S
If he's having "upside down" screen issues on Windows, then it is a Windows driver issue and has nothing to do with this thread on Linux drivers.
