Mafia II

What works

Shadows were previously broken with Wine 3.0→3.6 but are now working with this version of Wine.

Starting a new game/saving/loading/playing for a while etc. all seems to work as well as they did before with Wine 3.0.

What does not

The sky occasionally flickers - not a big deal but this game would be worthy of a Gold or Platinum rating if not for this issue.

According to earlier reports, some users reported regular crashing unless PhysX is disabled so that's something to keep in mind if you experience the game crashing a lot. I've only been playing with PhysX disabled and the game seems to be mostly stable - it crashed only three times when I did a playthrough using Wine 3.0, but I couldn't reproduce them & they may just be the result of game bugs.

Workarounds

For shadows to work on AMD GPUs a workaround is needed (or at least it was necessary with my RX480). Two registry entries are required; run these two commands to add them (this is the same workaround used for getting Fallout 3 to run on Intel GPUs):

reg add "HKCU\Software\Wine\Direct3D" /v VideoPciDeviceID /t REG_DWORD /d 0x402 /f
reg add "HKCU\Software\Wine\Direct3D" /v VideoPciVendorID /t REG_DWORD /d 0x10de /f

This appears to be an issue with the game itself as I've heard reports of issues with shadows on ATI/AMD GPUs on Windows too.

What was not tested

I have not done a full playthrough with this version of Wine, nor have I tested all of the DLC (beyond checking that the DLC campaigns can be started) or with PhysX enabled.

Hardware tested

Graphics:

• GPU: AMD
• Driver: open source

Additional Comments

This report is based on my notes and testing during the creation and maintenance of my wrapper for the GOG version of this game: https://www.gog.com/forum/mafi...

If you encounter a stuck loading screen, be aware that this is a bug with the game itself & not a Wine issue. I encountered this issue during chapter 10 during my playthrough with Wine 3.0 & had to restart the chapter from the beginning (use the "load chapter" option from the menu) to fix it.

Prefix configuration:

• CSMT was enabled
• Wine Mono and Wine Gecko were not installed

PhysX was installed using the installer used by Winetricks (PhysX-9.14.0702-SystemSoftware.msi, SHA256: 0a022e28accf5851be9d6577487cdcd3d3a3e2a8a21a64456b72b415c217f03c) rather than the installer bundled with the game.

Tested systems:

• AMD Ryzen™ 7 1700@ 3.7GHz, 16GB RAM, Radeon™ RX 480 8GB (main system)
• Intel® Core™ i7-2600K Processor @ 4.5GHz, 16GB RAM, Nvidia GeForce GTX 750 Ti
• Intel® Core™ i3-6100 Processor, 4GB RAM, Intel HD 530 graphics

All running Linux Mint 18.x with kernel 4.15.0-15 and stable Mesa from Padoka's PPA (for AMD/Intel graphics) or Nvidia's proprietary drivers.
