So I decided just for gits and shiggles to download and run SketchUp Checkup on my system. I didn’t believe there were any problems using SU 2017, but when I ran it, it gave me this error report:
The video card has in fact 4GB of RAM on board, so…um…what?
It is a glitch with the Windows reporting system that the Checkup application runs in the background, and happens with many types of graphics card. I am afraid that the Checkup app is not as useful as it might be until the developers have found a way to get more reliable information.
