Sounds nice. I love OOT, but on DolphinVR it was... the
only VR experience I've ever not been able to tolerate.
SM64 is doable for me, but OOT at 20FPS gave me massive headaches, eyestrain, I never wanted to try it again

and I happen to be the most motion sickness tolerant VR user I've ever met (out of several thousand)
However, this new thing says "30FPS upscaled to 90", and I couldn't ignore something like that. Even if it's just re-projected, I could handle that much better than the native 20.
I'll have to try this out though- fixed culling (big immersion and experience enhancer), draw distance, no HUD (HUDs are just a giant ugly transparent square a few feet in front of you in VC VR games usually), and a special texture pack specifically for it.
Only complaint there that's unaddressed is the "one joystick" movement style that Kaze used for this and SM64, but fixing that would require making an entire new camera system too.
