It’s late here but tomorrow I will try the VRWorks-Graphics-4.15 branch and have a tinker. I’ll also have a dig into the source to see if that gives any clues on usage/configuration.
I need this stuff to work to help justify upgrading to at 1080Ti. For that much money I want to wring every possible bit of VR performance out of it and ultimately out of a pair of them in SLI.
