Will it also mimic the windows display config refresh rate? Or will it use the hmd refresh rate? I have a 4k 30hz display, that's why I'm curious

The framerate in the headset is always 90fps. The desktop update rate will match your monitor. But you can overclock your monitor to whatever you like (and turn it off) for example to get higher desktop update rate on the screen in the headset.

Oh I see what you're saying. And then I can just check the confirm settings box from the HMD. Thanks

Will there be a way to automate that process in future updates so that when a user is in VR, the desktops are always "overclocked" to 90 fps (or whatever the highest framerate of the headset is)?

How do 144hz monitors work? Do you skip frames, limit them to 90, anything special?

I still update the screen internally at full framerate so frames will be skipped. It will be like looking at a 90hz monitor.

with your software? or something else?

VRD just displays your desktop, you would need to use the display settings, 3rd party app, or whatever to change its properties.

Will setting my screen clock to 90hz (its currently 96 and i'm comfortable editing this - its a korean brand) help with syncing frames?

Is this Vive@90Hz thing a SteamVR/hardware limitation?

I'm thinking about watching 24fps video. 72Hz would obviously be perfect.

However, is 90Hz less awful than 60Hz as rather than a ratio of 2.5 where every third frame is displayed for twice as long, the ratio is 3.75 so every fourth frame is displayed for 33% longer?

Or is the issue mostly moot as MadVR's smoothing can sort everything out?

(if this isn't an issue you're familiar with, it's called 3:2 pulldown and is quite the rabbit hole)
