Bug #: 30299 Summary: Graphical glitches AMD/ATI graphic cards in some specific games. Product: Wine Version: 1.5.0 Platform: x86 OS/Version: Mac OS X Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: paulthetall@gmail.com Classification: Unclassified
There are a list of games which do work fine on the Mac with Nvidia graphical Cards, but give massive graphical glitches on AMD/ATI graphical Cards. Examples of games which are infected with the issue:
Red Faction Guerilla Tombraider Underworld Assassin Creed Lara croft and the guardian of Light Crysis 2 The saboteur Lord of the Rings War of the North The adventures of Tintin and quite some others which are infected
UseGLSL=disabled does not work in those cases and also changing display settings in the game (like shadows and such which might sometimes help in other games with other graphhical glitches). So this passes that part.
There is a demo for Lara croft and the guardian of light which you can download to test http://store.steampowered.com/app/35130/
Linux users probably won't have this issue becasue they can install graphical driver updates from the Graphical card developers. Apple on the otherhand have not that luxury and we are stuck and dependent on apple updates. However somehow Transgaming with his Cider wrappers which is mostly wine overrulled this issue for AMD Radeon/ATI cards. So it is possible to run this kinda games on the Mac. Most likely because Chris bently from AMD Supported Cider so it might be they give some fixes for this kinda issues to Cider which they used to get it run properly for AMD Radeon card Macs.
So to you guys the question to look into it. You can use the deo te reproduce it on an AMD/ATI Mac to get the right debugcode. Also I made a video which shows the graphical glitches i talk about up here: http://www.youtube.com/watch?v=LH1aSEH3mQg
