This looks really great! Also, some recent updates on motion sickness—Gabe mentioned it's extremely rare, with almost no cases reported.
Motion sickness relates to how the brain processes visual input versus physical movement. A high refresh rate helps minimize discomfort by keeping images stable. If tracking is nearly perfect, it lessens the disorientation. Watching a screen move differs from being fully immersed in a virtual environment where sensations align. In games like Portal, this mismatch can trigger nausea. This demo appears very static with little motion, which might affect how your eyes and brain interact. I’m curious if earlier demos had similar issues with eye movement and whether that impacts sickness.
