I got my vive a couple of months ago and I had it working fine with my laptop (alienware m15) and I booted it up yesterday and it was incredibly laggy.
The ms was hitting 111ms at its high and then swinging back down to 6.
I shut everything down and tried again and it would work for one song of Beat Sabre and then just start lagging again.
I don't really know what the issue could be...
Alienware m15
Intel Core i7-8750H CPU @ 2.20GHz 2.21 GHz
16gb of RAM
Windows 10
intel(r) uhd graphics 630
