The bit that's not obvious is how the low weight and short leverage of the headset affects lag. When you are wearing a heavy headset that extends far from your face, it's not just the rendering latency and screen latency that affects the disconnect between your head movements and what you see. The headset physically lags behind your head motion because it has inertia. The total lag is the sum of the digital and physical lag. So, improving the frame rate can only get closer to the physical lag. And, that's on top of the practically-instant pixel response of OLED vs LCD. All that is to say that there are physical explanations for why 90 and even 75 Hz is better in practice than people would reasonably expect on the BSB. I can confirm first-hand. And, so have many reviewers.
