Bug ID: 46240
           Summary: Champions of Regnum fps not smooth
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Hello,

There is randomly but very often fps drop with wine version 3.x.
Version 2.x don't had this problem, always 60fps with vsync turned on.

V3 either drop to 0 every x seconds either (for latest 3.21) drop to around
30fps randomly. Maybe it's related to input lost that put the game in energy
safe mode or something like this, no idea.

CPU is 100% (stats from game alt+i) in V3 compared to 50% or 60% in Wine V2.

Wine and game in 64 bits on a i7 8600k + r9 280x on MacOS

Thanks

Which 3.x versions have you tested?

Does disabling csmt help? (In the registry, set
HKEY_CURRENT_USER\Software\Wine\Direct3D, value csmt, to DWORD value 0).

If you have the ability (and time), a regression test would be helpful:

I have test a lot of Wine 3 versions and the last good version is 2.0.4.

I can't find this in regedit, does it mean it's disabled for devel version ?

Right; I ask more in the interest of finding the earliest known bad version.

The value doesn't exist by default; you can create it.
