The issue of the game failing to open is common and seems to be unrelated to
Intel, according to https://spcr.netlify.com/ (on raw reports, as it's unlisted
on Steam).

There is one important detail: DiRT 3 has DirectX 9 and DirectX 11 modes. DX11
mode can use DXVK while DX9 uses OpenGL translation from Wine.

One way reliable to know if you are opening the game in DirectX 9 or 11 mode is
in the game opening. If the first small square shows the DiRT 3 logo, you are
using DX9 mode, which does not use Vulkan and won't be able to reproduce this.
With DX11 mode, the small square does not show the DiRT 3 logo (some graphical
bug, looks like).

There is one particular configuration file at
${WHERESTEAMISINSTALLED}/Steam/steamapps/compatdata/321040/pfx/drive_c/users/steamuser/My
Documents/My Games/DiRT3/hardwaresettings/hardware_settings_config.xml

One of the XML settings is:

<directx forcedx9="false" />

This settings has to be set to false, otherwise DXVK won't be used. If set to
true it's using DX9.

I recommend enable the DXVK HUD by setting in the DiRT 3 launch settings on
Steam the following:

DXVK_HUD=1 %command%

So you can be sure that the game is using DXVK.

It appears you are using DX9 because of the square that shows the logo, with
DX11 the square should be empty.
