I have installed 2019 SP0 and a clean install of Quadro certified driver 411.63 with an NVIDIA K2200 however I have had to turn it off due to unusable display performance while creating an in context part within an assembly.
The first view is with Enhanced Graphics Off and the second with it On. Its not exactly the same framing but you can see the inversion and lack of image in the second view.
Appreciate this is beta software and I guess this is some feedback on that.
Any suggestions as to what may be causing this gratefully accepted as it would be great to be able to use the new feature.
