http://bugs.winehq.org/show_bug.cgi?id=59123 --- Comment #3 from Zak <user.pecheniok@gmail.com> --- Got my hands on a friend's ivy bridge/terrascale 3 laptop. The performance drop is identical on both gpu's there and to mine. It almost feels like amd specifically either has a driver bug and/or is more affected because when I fullscreened the window in the main menu, the fps dropped from 40 to 15(about the same drop to my igpu), while only from about 25 to 17 on ivy bridge. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

On an AMD RX 7800 XT, if I maximize the game window and wait for the music to start playing on the title screen, I do see the framerate drop to 40-50 FPS in Wine 11.0-rc1, but it stays at 60 FPS in Wine 10.20. `git bisect` says: ce44dd0ba41b88f6b8eb626863c3358b75aca66c is the first bad commit commit ce44dd0ba41b88f6b8eb626863c3358b75aca66c Author: Rémi Bernon <rbernon@codeweavers.com> AuthorDate: Tue Dec 2 12:32:28 2025 +0100 Commit: Alexandre Julliard <julliard@winehq.org> CommitDate: Fri Dec 5 11:09:17 2025 +0100 wined3d: Remove now unnecessary pixel format restoration. wglSetPixelFormatWINE now sets the internal pixel format privately on each DC, and it is unnecessary to restore the window pixel format. That call is even undesirable as it allocates and destroys a private OpenGL drawable when the DC is acquired, its internal pixel format is set, and the DC is then immediately released. dlls/wined3d/context_gl.c | 44 ++------------------------------------------ dlls/wined3d/wined3d_gl.h | 1 - 2 files changed, 2 insertions(+), 43 deletions(-) -- Do not reply to this email, post in Bugzilla using the above URL to reply.
