More control over contrast/brightness. I think something between 0 and 1 contrast is a sweetspot where we won’t see any color “crush.” Maybe increments 0, 0.5, 1, 1.5, 2, etc, or even better, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, etc.
Short push of the power button brings up the SteamVR menu, and a mouse dot in the middle of the view can be used to access desktop/settings/etc without using a controller(use head as a mouse pointer). The Index has this feature and I really miss it while using a Pimax headset. When racing and desiring to check the time, or a steam message, or change a setting, I currently have to find a controller, turn it on (and waste battery), and navigate with it, where with an Index I could just press the power button and then use my head as a mouse and press the power button again to “click.” The way to turn off the SteamVR settings is to point the “mouse” pointer off the settings/desktop screen and short click the power button again.
Enable lower refresh rates for 8K-X like 64Hz: great for older flight sims like DCS or X-Plane
Backlight controls for 8K-X (potential per screen, my left screen seems slightly brighter)
Outside of PiTool: provide easy to understand, step-by-step instructions that can be published to game developers explaining how to update their games so that they no longer need parallel reprojection.
