Not that I’ve found. When did this happen with Whirligig? Seemed okay as of my last use maybe two weeks ago.
I’ve actually been using mostly Heresphere - found that if you switch on the SteamVR OpenXR runtime rather than using Quest’s, it eliminates a lot of the lag issues. Not all, some videos are bad for some reason, but you can also just seek a second or two backwards or forwards when it starts doing it and it usually fixes it. And the visual quality strikes me as massively superior to Heresphere.
Heresphere on the headset itself is the best option by far but it’s annoying to have to put the vids on the headset because of limited space.
