http://bugs.winehq.org/show_bug.cgi?id=59594 Bug ID: 59594 Summary: OpenGL Fixed Function Textured Triangle Performance Regression from Wine10 to Wine11 Product: Wine Version: 11.3 Hardware: arm OS: MacOS Status: UNCONFIRMED Severity: normal Priority: P2 Component: opengl Assignee: wine-bugs@list.winehq.org Reporter: checker@d6.com Created attachment 80663 --> http://bugs.winehq.org/attachment.cgi?id=80663 repro program for perf regression I have found a significant OpenGL fixed function textured triangle rendering performance regression from Wine 10 to Wine 11 under MacOS on an m1 apple silicon laptop. I found this when running my video game SpyParty, but to report it I narrowed it down to the very simple attached program that repros the issue. On the same machine, both with clean .wine folders, same executable, if I build and run the attached fontperf.exe, it gets about 5x better performance on Wine 10 than on Wine 11 (120fps vs 24fps). The program updates the title bar once per second with the instantaneous FPS and the smoothed FPS. Let me know if you need any more information. Building the app with the mingw command line at the top of the source file should repro the problem. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
