BTW, Dx12 doesn't work on older windows GPU cards. Use vulkan, that build works fine. It's sad that Godot seems to separate graphics functions like this.
I assumed the dx12 build would have better compatibility with older hardware but there seem to be more people having problems with it than the vulkan build.
The windows build is supposed to switch to the the other rendering API automatically at launch if there are any compatibility issues, but I guess it crashes before it can do so.
