I'm a VIVE user and have just fixed a lot of jitter issues by getting rid of Oculus Home and Revive off my system.
I've been doing a lot of tinkering today so can't be absolutely certain it was THE fix but worth a shot to any other vive users that have the oculus software installed and are having jitter issues in 2.5 too.
Spec:
Ryzen 5 1600 @stock, RX580 8GB , 16GB Ram , SSD
