Bug ID: 47380 Summary: GT Legends: Slow graphics and 100% CPU usage Product: Wine Version: 4.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d Assignee: wine-bugs@winehq.org Reporter: timschumi@gmx.de Distribution: ---
GT Legends does have a significant graphics slowdown when running in wine, while a single CPU thread is locked at 100%.
When looking at the process in a profiler, most of the time is spent in the function wined3d_cs_mt_finish() (and I guess the wined3d_pause() function within, which doesn't show up in a profiler due to being inline).
This seems to be a regression as well, since there are videos (for Wine 1.9.10, [1]) and AppDB entries (latest entry for Wine 1.7.0, [2]) that claim that the game was running fine on earlier releases of Wine, but I wasn't able to find the exact commit that introduced the regression so far.
Patches from wine-staging don't help either. Please let me know what type of logs would be the most suitable ones to debug this, since a normal +d3d log seems impractical with over 13MB in size.
