--- Comment #2 from Béla Gyebrószki <gyebro69 at gmail.com> ---
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:

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.
