Alright, maybe I'll make another build, but it will be a while.
Im not sure if there is a way to do these things without a build. Maybe you can configure the sync in the os or graphics card settings.
The dead zones, we are using unity's new input system, which settings should be stored in json format. Though I'm not sure if it is stored within the binary.
I'll notify this thread if I make another build 😉
