Windows 10 Preview? I will update the profile system to support the game, however you can try using the iLegacy Performance Switcher to resolve the issue as it is capable of resolving artifacts. (Well, for some games.) Yea, I forgot about Vista. I suppose I could change the download link or incorporate an alternate method that's universal. Also I am considering to recode the Alternate installer in c++ for more options but I haven't decided yet, so we'll see how that goes. I think I will have to take a look at your system using Team Viewer, so I may gain a better understanding of the problem you are facing. To be honest I haven't had much experience with dynamic switchable graphics, even the profiling system I'm working on only supports Fixed Switchable graphics as dynamic Switchable Graphics requires a bit more work. Anyways, if we have team viewer session it might help shed some light on things.
