Bad framerate....15-16 MS in steamVR performance window

Anybody have any ideas why Borderlands 2 VR PC would have such a bad framerate.

1080 ti
intel 6700
SSD drive
16gb ram

Nothing i change in the the settings seems to change performance…ive turned everything down as low as it go…still getting 15-16 ms. This game runs way worse than Fallout4 VR…all my other games run normal with good framerate…If i cant figure it out i’ll have to refund and leave a bad review…game is unplayable like this.
