Grim Dawn won't run on dGPU
Hello everybody! I waant to thank you in advance for your support!
I have a laptop with the usual two gpu (will post some system summary in the first reply), and the dedicated one, which is NVidia, is usually automatically selected by the couople of games I usually play with heroic (Timberborn and Citizen Sleeper 2)... But Grim Dawn seems fond of using the integrated GPU whatever the cost (I'm certain of this because I can't find it in process list).
I tried switching a couple of versions of wine-GE, proton-GE and proton-hotfix, and I manually set the following environment variables
without any result... And I think the root cause of my issue might be related to Vulkan version, the same cause of 🆘-supportGrim Dawn failed to initiate graphics engine, because I also made the following tests:
TYVM!

- adding the environment variable with the dGPU name as value will cause the game to fail graphics engine initialization, with a in the logs. Installing all the winetricks mentioned in the linked thread don't change the result.
- unchecking all the DXVK options in the configuration window will actually run the game on the dGPU, loading the main menu with heavy glitches and an immediate crash after starting the first game...
TYVM!
