While I agree that officially OpenMW “isn’t finished”, I have completed a playthrough with it in the past and it already works very well. IMHO it’s also the future for Morrowind as a whole. For my current playthrough I went back to MGE XE because of the (currently) better looking distant land feature, but OpenMW support should be something worth considering. (Although the “proper” way of implementing VR for it would probably be an addition to OpenMW’s codebase itself, but I guess including OpenVR libraries isn’t really an option for a GPL-licensed software).
Best regards,
