I just installed 2016 SP3 and discovered that the quality of my RealView graphics is substantially degraded.
I finally updated to a supported graphics card a few months ago - the NVidia Quadro M4000, with the correct Solidworks driver. The quality of the graphics is stunning. Was stunning. And then I installed SP3 last night, and it isn't quite so nice anymore. Same model - same lighting - nothing changed.
Even the icons that show up in File Manager have a better image quality that what I get onscreen in SP3 now. I was thinking that there might be a graphics driver update, but no.
