Bug ID: 45482 Summary: jade empire default cpu affinity is only with cpu1 and performance are dropped Product: Wine Version: 3.12 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: andy86@fastwebnet.it Distribution: ArchLinux
If don't know is a valid wine bug or a game bug, but reading appdb seem not present on old wine version < 3.7 or less.
When game is started performance is very poor, seem < 10 fps in main menu, unplayable at all.
Investigating I discovered that game use only 25% of cpu at default, looking for the cause, I check cpu affinity in wine taskmgr and it's have just one check of four (cpu1).
I check all box, and game start to use more of 25% cpu, and performance increase to 60fps stable.
Problem is that cpu affinity isn't saved, and operation need repeat every time that game is started.
