After a lot of research online, I didn’t find a fix for that. It seems the error come from Unreal Engine 5 backend and not from the game itself.
You can force the game to run using DirectX11 backend instead of DirectX12:
- Right click on Appulse.exe
- Click on Properties
- Add ‘-dx11’ at the end of the ‘Target:’ line like in the screenshot.
I hope it will work ! Tell me if that’s not the case.
An update is coming to address some bugs and add video settings, VSync will be included.
