Thank you very much!
Vsync is enabled with -v launch parameter.
Unfortunately I can't promise VR support in any foreseeable future. It is not in my scope, and I already made some technical decisions, that will probably make it even harder to implement.

Or try getting access to CoralVR (I hope, it is still alive)
