And last thing, the tracking is weird, sometime “the floor is moving by itself” even in pimax VR home.

Does this sound like my case?

I also have fluctuations in 8K.
I don’t know if everyone has it. But this is noticeably expressed in AssettoCorsa, and is also present to a small extent in SteamVR Home.
It feels like the space around you oscillates, twitches a little, smoothly. But does not leave, as with drift.
