1. Sound, some loud statics, like one of the ambient sound files was broken. Hearable every few seconds.
2. Graphics, the light water reflections (torch light for example) sometimes does not look correctly, like the shader went nuts. Reflection becomes almost solid white/grey elipse with red/green colors on the borders.
None of these issues happens on windows installation on the same machine using the same save game.
Tried "reinstalling" the game, didn't help.
Computer is Early 2010 macbook pro 13" 2.4ghz, nvidia 320M. OS X 10.6.4 fully upgraded.
Mac log is made clean, meaning:
I removed the old one, run the game, loaded the included save game, played a little to reproduce both issues, quit the game.
Windows log is the one I already had on my disk, can't run the game on windows now. But the Cistern level was played in this log, maybe not on exactly the same savegame.
