I'm seeing a pattern in the GPU hangs (I don't know how to interpret them,
sorry). The GPU hangs are happening mostly when the track is in the morning or
evening. With other climates I'm no longer seeing GPU hangs.

I noticed the shadows blink when some of the GPU hangs happened. 

One GPU hang happened after selecting the track, before appearing the options
such as "RACE" and "VEHICLE SETUP". This is the screenshot when it happened:

Another happened when watching the replay, unfortunately I forgot to echo 1 and
have no card0/error. This was the screen: https://i.imgur.com/d02ptX7.png

A third one happened (the first in a place other than Monte Carlo since the
second patch) when watching the replay too. The screen can be seen at

I have increased verbosity from the logs. I have noticed two logs related to
DXVK. The log called dirt3_game_dxgi.log has: 

info:  Game: dirt3_game.exe
info:  DXVK: v0.62-2-g4ab5682
warn:  OpenVR: Failed to locate module
err:   Required Vulkan extension VK_KHR_get_physical_device_properties2 not
supported
err:   Required Vulkan extension VK_KHR_surface not supported
err:   Required Vulkan extension VK_KHR_win32_surface not supported
err:   DxvkInstance: Failed to create instance

The log called dirt3_game_dxgi.log has:

err:   D3D11CreateDevice: Failed to create a DXGI factory

I have noticed that from the three extensions shown in the error, only
VK_KHR_win32_surface is not available. May the lack of this particular
extension be the cause? But isn't it exclusive to Windows (as it has win32 in
its name)?
