Thanks @doublevr
I've tried downloading the BETA DeoVR channel client on Quest 3, but that version just crashes on app start, so can't test if it is better.
As I mentioned in my post, a good example I've seen where this is a consistent issue is 'sensualkattt'. So this should be a good place to test\start.
In testing this stream, I see lag even just on her SLR stream in any browser.
On Quest 3 DeoVR app, the stream opens perfect with no lag, but then a few seconds in (random) it hard-freezes, or goes super slow-mo and then rubber-bands, but never recovers on its own.
Same model, on Index\Vive it never freezes, but the lag is same as on browser, and is unbearable.
On all other streaming services for this cam, there are basically no lag\freezing like this.
I've drilled down with details into this cam because I know testing an issue requires reproducibility, but it isn't limited to her stream only.
Thanks for checking - pls let us know how we can test or what else we can try...
