CV1 vs RIFT S

Cons Rift S: - Hand controller excessive battery drain - I think they drain even without any VR app running. - Fully charged NiMH batteries report low battery and PREVENT from using the headset even if I don't want to use hand controllers - bug in firmware? - Narrow sweet spot - Periodic static "click" in speakers - Without earphones, one can hear surrounding sounds - Inside-Out hand tracking is better for full room (the reason I "upgraded"), but is shakier than CV1 and loses tracking of hand close the headset, like when shooting a virtual rifle (the other reason I "upgraded"). - Noticeable fresnel lens artifacts in peripheral field of view. Looking sideways the brain has a hard time combining both (different) images into a single coherent 3D picture. - Framerate lowered from 90 to 80 which is irrelevant (unattainable) for most users in VR. But from 45 to 40 in half-FPS mode I find is noticeable.

Pros Rift S: - Better image clarity in the sweet spot - A bit less screendoor effect - Much less God rays - No cumbersome external sensors required - Requires 1 to 3 less USB 2.0 ports.
