[Bug 27618] New: Very slow wine Opengl performance with ASUS 1215N
http://bugs.winehq.org/show_bug.cgi?id=27618 Summary: Very slow wine Opengl performance with ASUS 1215N Product: Wine Version: 1.3.21 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: opengl AssignedTo: wine-bugs(a)winehq.org ReportedBy: turgut(a)kalfaoglu.com As documented in: https://github.com/MrMEEE/bumblebee/issues/313 optirun32 wine wow.exe -opengl produces a warcraft game that's unplayably slow. However, the same hardware plays wow at a 45FPS when booted from windows7. It was determined that it was a wine issue, after it was researched by the Bumblebee project. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Bumblebee uses VirtualGL and the use of VirtualGL comes at an additional performance hit. The way things work when you use VirtualGL is that all 3D content is rendered on the Nvidia GPU. In order to show the images on your screen, every 3D frame has to copied back to system memory and copied back to video memory on your Intel card. This is quite slow and stress the PCI-E bus quite a bit (especially on laptops where you typically have much less bandwidth). It directly slows down the game as well because this is all happening during the 'glXSwapBuffers' call the game makes. On Windows the Nvidia drivers use similar VirtualGL-like tricks to render on the Intel GPU, but there are a lot more optimizations are in place (and there is likely more direct interaction with the Intel driver). At least this issue is definitely not a Wine bug. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
