Bug #: 30470 Summary: Certain programs (rFactor, GTR 2 (and maybe VSTHost)) now running slowly Product: Wine Version: 1.5.2 Platform: x86 OS/Version: Mac OS X Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: dbmmbr@gmail.com Classification: Unclassified
With Wine (on Mac OS X), starting with version 1.5.1, the games rFactor and GTR 2 run slowly / run with laggy jerky video (which they didn't do so with Wine versions 1.5.0 and earlier).
(And, also, I think that, with Wine (on Mac OS X), starting with Wine version 1.5.1, the program VSTHost maybe runs using more CPU power? / runs less efficiently? (than it did with Wine versions 1.5.0 and earlier.))
