[Bug 41394] New: 3DMark2001se 'Car chase' speed regression on mesa/nouveau
https://bugs.winehq.org/show_bug.cgi?id=41394 Bug ID: 41394 Summary: 3DMark2001se 'Car chase' speed regression on mesa/nouveau Product: Wine Version: 1.9.16 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs(a)winehq.org Reporter: randrik(a)mail.ru Distribution: --- After upgrading wine to ver. 1.9.18 I noticed strange speed regression. After bisecting wine I found this commit was source of it: first bad commit: [b62f4139eda58e8e25cbc58864fcea2599a20e97] wined3d: Swizzle D3DCOLOR attributes in the GLSL FFP replacement when necessary I'm using nv92 (GeForce 8800 GS) video card with relatively new kernel (4.8.0-rc7-x64+) and 32-bit Slackware OS with many manual updates, including git Mesa drivers. Initially I blamed mesa for speed regression, or my specific build of it, but after testing Mesa 12.0.3 and seeing same very low speed there I tried wine bisect first. May be there is interplay between some bugs, or nouveau simply can't handle slightly different kind of load. But most other tests in this benchmark works fine, and older 3DMark2000 also speedy. I tried to make apitrace of this issue but under apitrace both good and bad commits played 'car chase' scene (low/high detail) smoothly. Without apitrace running bad commit mostly slows down to 0-1 fps even on low detail scene.

https://bugs.winehq.org/show_bug.cgi?id=41394 --- Comment #1 from Matteo Bruni <matteo.mystral(a)gmail.com> --- That's weird indeed, Mesa on your GPU should support ARB_vertex_array_bgra so this patch should not make any difference on your setup. It's also pretty suspicious that it's not slow with apitrace. I have downloaded the traces but I haven't looked at them yet. I also have a box with a similar GPU, I'll try to reproduce there (if I can manage to start that box again, at least...) I guess you could also try to attach (or link to, if it's too big after compressing it) a +tid,ddraw,d3d,d3d_shader log with current Wine, maybe that will give us some clue. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Using wine wine-2.2-33-g60c98ca on linux 4.10 git / mesa Mesa 17.1.0-devel (git-5398d00) I can't observe any serious slowdowns even if I set cpus to 1.4Ghz speed (current minimum) Thanks for fixing this! -- Do not reply to this email, post in Bugzilla using the above URL to reply.
