Hello @Steap, unfortunately the Vulkan driver for your Ivybridge generation Intel graphics provides an incomplete implementation of the graphics API and using the PROTON_USE_WINED3D runtime option is not considered supported, which makes your system unsupportable in general for Proton. This is something you'd need to reproduce with a vanilla wine install and report your findings to the upstream wine project so they can take a look.
Compatibility Report
System Information
I confirm:
Symptoms
The graphics freeze randomly and do not "unfreeze". The sound is still working and it seems the game is still running in the background.
This might be a regression as someone else seemed to manage to run the game 2 years ago.
On ProtonDB people seem to use cnc-draw to get the game working. If this is truly required, this should be automagically installed/configured when installing the game in Steam.
Reproduction
Play the game, and the bug occurs within a few minutes. Unfortunately I cannot find a better way to reproduce this.
