Bug ID: 45436
           Summary: HoMM 3: Horn of the Abyss severe performance
                    regression with non GDI mode from HoMM3 HD
           Product: Wine
           Version: 3.12
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

There is severe performance regression with non GDI mode with this game, when
HoMM3 HD Launcher is used. The regression occurs both with vanilla and staging
3.xx wine versions. I also tried and PBA to no avail. If I choose 32-bit GDI or
32-bit True (stretchable) GDI, the game running fine. All other modes has slow
performance problems and some of them are very serious - with mouse, scroll and
horse movement lag. I tried Nvidia proprietary driver and Nouveau with the same
result. With Wine 2.21 all is working correct and there isn't performance
problems at all.

I confirm that this problem is still present in Wine 4.0. I tested with HoMM
III (GOG.com) + HoMM III HD unofficial patch.
Symptoms are as follows:
- slow unit movement and scrolling
- mouse cursor lag
- when I'm constantly moving the mouse over the exploration map, animations
come to a halt
- ending a turn (when computer players are taking their moves) takes a very
long time.

Disabling CSMT gets rid of those problems.

Steps to reproduce the problem:
1. install HoMM III. I tried the GOG.com version, but it is probably
reproducible with the retail version as well.
2. Download and install the HD patch, currently at version 5.0 RC43: 
https://drive.google.com/open?id=15o9pql8TwOAwqiRAHnuj13qr8vzmh6fn
HoMM3 HD Latest.exe (13 M, md5sum: 7c3663fface48a8ae003e8c0534e58e3)
Make sure you select the GOG installation directory when installing the patch: 
C:/GOG Games/HoMM 3 Complete
3. Start 'HD3 Launcher.exe', 'Heroes3.exe' should be selected in the drop-down
menu, then click <Create HD exe> and save the modified .exe file.
4. under Graphics section select <32-bit True>, choose a screen resolution and
enable full-screen mode.
5. Click on <Play> to get in the game.

Tested on Wine version 6.1 and not confirmed.
None of the symptoms described in the previous (2019-01-23) post are present.

Steps taken:
1. Installation of full HotA package (HOMM3 + HD Mod + HotA) from the official
HotA website at https://h3hota.com/en/download 
2. Updating HD Mod to the latest version (5.2 RC 28) using HD_Launcher.exe 
3. In the drop-down menu, selecting <h3hota HD.exe> as the game executable.
4. Under graphics section, selecting <32-bit Direct Draw>, native screen
resolution and full screen mode. 
5. Launching the game.

Work as expected without performance problems.
Also works as expected if we use HD_Launcher.exe to "Create HD.exe" from
h3hota.exe Because of that, the problem, if still present, is believed to not
be related to the creation of HD executable, and is thus presumed to also be
absent when installing HD Mod and HotA on the retail or GOG.com version.

Other Graphics modes tested (as the original report mentioned performance
problems in all modes but 32-bit GDI/True GDI), with no performance problems
noticed: <16-bit DirectDraw (original)>, <16-bit DirectDraw (auto switch)>,
<(stretchable) 32-bit OpenGL by Verok> with Stretch filter options set to <xBRZ
x2> and <+Hermite>.

It needs mentioning that HD Mod no longer provides 32-bit True as an option, it
seems it was replaced by Direct Draw, download link provided in previous post
is no longer valid and HD Mod website does not provide the possibility to
download past versions of modification, making complete replications of
previous tests but with newer Wine version impossible.
