Warcraft III

Warcraft III is a DirectX 8 game. By default the game seems to be running in OpenGL mode under GE-Proton10-29 which is borked. Resizing the window causes the lighting to break.

The following env var is supposed to make it use D8VK to run using Vulkan:

export PROTON_ENABLE_D8VK=1

Unfortunately this doesn't seem to work.

Working fix

Use GE-Proton9-27

export WINEDLLOVERRIDES="d3d8=n"

• Download dxwrapper v1.5.8100.25 from https://github.com/elishacloud/dxwrapper/releases/tag/v1.5.8100.25
• Put d3d8.dll, dxwrapper.dll, dxwrapper.ini in the root of the install directory
• Edit dxwrapper.ini:

D3d8to9                    = 1

Should be fixed now.
