AlpakaDream: I get a warning when I start the game using Windows 7, that multiplayer won't work anymore on Win 7 / 8.
Offline gameplay however works fine.
fsbarbero: Do you have an nVidia or AMD graphic card? My graphic card is nVidia GTX 1070
What version of graphics driver are you using? I'm using 472.12, the last driver for Windows 7/8. Drivers after that version are only security patches and doesn't include any fix or modifications.
Have you made any additional modifications to your system to make the game work for you, perhaps by modifying the Vulkan drivers? As far as I know, NMS from 4.15 version onwards uses Vulkan 1.3 version, that is only supported by windows 10/11. Maybe this is why the game is trying to use OpenGL instead of Vulkan in my system. I don't know how to force the game to use Vulkan instead of OpenGL.
