What black magic did you have to do to get Myst III to run fine on Windows 10? I tried it a couple months ago and it was so slow and janky and low-res that it wasn't playable. (Maybe because I was using a USB CD drive?)
The one that gave me the most troubles was Riven (before I got it from GOG). For this one I had to do some mumbo-jumbo to finally get a full screen yeah.
