World of Warcraft patch 8.1.5: a lot of trouble for Wine users
legluondunet 13 Mar, 2019

Hello,
FYI the last WoW patch 8.1.5 have a lot of Directx changes:

New Graphics APIs in 8.1.5
In 8.1.5, we are making some improvements to how World of Warcraft uses DirectX. In essence, our old DirectX 11 is now called DirectX 11 Legacy, and our new DirectX 11 is multi-threaded. More details on each DirectX version is below:

  • DirectX 11 Legacy

  • A single-threaded rendering backend. This is provided to be the most compatible with older hardware, operating systems, and drivers. This is also the least performant. This is very similar to the functionality of DirectX 11 in 8.0.1.

  • DirectX 11

  • A new multi-threaded rendering backend using DirectX 11. This should improve performance for older GPUs or operating systems that don’t support DirectX 12. This is new for 8.1.5.

  • DirectX 12

  • A multi-threaded rendering backend using DirectX 12 for hardware, drivers, and operating systems that support it. There are some performance improvements in 8.1.5, but it is mainly the same as the 8.1.0 release.

    The game now crashes for a lot of Wine users. An issue is already open on dxvk github, but it seems Nvidia related:

    Linux users who use AMD does not seem to suffer from this update, someone could confirm that?

I'm pretty sure they don't test their games against wine and dxvk.

Mentality change at Blizzard? It's new they gave a little support to Linux users.

From my side, I reinstall Battle.Net with Lutris as Lutris dev uploaded a new script to help wine users to play WoW without crash. Don't forget to move your WoW game folder on another place before to reinstall Battle.Net.
I played more than one hour, it's stable and fast.
It's impressive how the wine community and actors was reactive.
Lot of thanks to Philippe and Lutris dev.

FYI:
Blizzard fixed bug from 8.1.5 version, hacked version from Dxvk is no longer needed.

QuoteI just needed to run "sudo apt install libvulkan1:i386" to get it to work again.
Strange you didn't need to install it before, vulkan librairies in 32 bits are essential for Dxvk to run games in 32 bits, and they are a lot...
