Bug ID: 38169
           Summary: The Settlers 3 eats a full CPU core, even on a Intel
                    Core i7
           Product: Wine
           Version: 1.7.34
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Console output with Wine 1.7.34

This has been a problem for ever when running "The Settlers 3" on Wine, so it's
time to make it a bug: even though this year-1998 game runs perfectly on
Windows on a Pentium II CPU(!), it eats up a whole single CPU core when used
with Wine.
This results in the curious situation, that even with an Intel Core i7 quad
core 2.2GHz CPU, the game feels slow on Wine...

Before this gets duplicated: this bug is different from Bug 32478. While in the
past the game had also on Windows with a multi core CPU the every few seconds
occurring lag described in bug 32478, it was somehow fixed after some
Windows-updates (I guess it must have been done by a Windows "shim"), the
multicore problem can easily be workarounded by starting the game with "taskset
-c 0 wine s3.exe". For the problem I'm describing here there is no known
workaround as of now.

Attached is a console log of 15 seconds of running the game (+ a few seconds in
the menu).
Settlers3 was started with the following command:
WINEDEBUG=warn+all,+loaddll,+message,+msgbox,+wine_d3d,+ddraw,+d3d_draw,+d3d_surface,+d3d_texture,+d3d,+dplay,+dplay,+dpnhpast,+cursor,+bitmap
taskset -c 3 wine s3.exe

This can be easily reproduced with the free demo version of the game, which can
be downloaded e.g. here:
http://s3de.siedler3.net/ftp.bluebyte.com/demos/eng/settlers3amazons/s3a_dem...
.

If the attached log is not enough, I can try to enable more log channels (but
which ones?). I'd like to help as much as I can to fix this, as besides for
eating the CPU, the game runs much better on Wine than on newer Windows
versions.

+1, using wine 1.7.29 via wineskin.

Interesting observation: when using the other available open source DirectDraw
implementation (DXGL: https://www.williamfeely.info/wiki/DXGL) instead of the
one from Wine and also enabling VSync in the game settings, the game consumes
50% less CPU.
Unfortunately, this not an usable workaround because of a DXGL bug
(https://www.williamfeely.info/bugzilla/show_bug.cgi?id=44).

This is a combination of two issues:

- Lack of implementation of ddraw7_WaitForVerticalBlank (bug 9154)
 - CSMT optimizes for raw fps resulting in higher than necessary CPU usage (bug
45761)

Bug 9154 is very likely the reason - see also comment #2.

Regarding bug 45761 I have my doubts, as Settlers 3 was always so slow with
wine - not just after CSMT landed...

Bug 38169 depends on bug 45761, which changed state.

I can confirm the bug with Wine 3.0
On a notebook, the heat Settlers III generates is by the CPU load even with
only one core assigned is "impressive" (in a negative way) and battery runtime
is of course extremely low.

https://bugs.winehq.org/show_bug.cgi?id=9154#c27 mentions a possible solution,
but this has not been implemented yet on newer versions of wine, right?

Bug still occurs with wine-5.1.

Interesting thing: it does *not* occur for me anymore with wine-5.5-staging
*if* I disable "CSMT" in winecfg - in this case the game uses less than 50% of
a single core (still more than on Windows, though).

If CSMT stays enabled (the default value), then the problem persists.

Thank you for the hint. 
I'm eagerly waiting for Wine to not toast my laptop when Settlers 3 is running.
(this issue creates an excessive amount of heat and drains the battery in less
than one game with a core i7 7th generation, although it should run on a
machine with less than 200 Mhz ;-))
Maybe that setting buys some time.

Does the bug still occur with wine-6.11?

Yes - tested with 6.19.
