Stuttering in VR after windows 10 update

[causticlime]

I recently went from windows 8.1 to windows 10 after upgrading CPU.

before the upgrade VR was fine after the update i get constant stuttering/frameloss when in VR

Tech specs:

Ryzen 7 3800x

16GB ram
AMD r470x GPU

 

i have tried a complete clean install and reinstalled drivers to ensure they are fully up to date.

CPU/GPU usage never goes above 20% so its not a hardware issue.
