Wow, I didn't even know there was a CD version of Myst 4. I only ever saw a DVD one in shops and it made me really glad I had a DVD-ROM drive. I've never heard of the "famous 4 second load/wait time" but even my DVD copy was always pretty sluggish. I replayed it recently on my new computer and it was as sluggish as ever despite an abundance of memory and CPU time.
To be honest, I think it's just not as well made a game as the first three (in terms of engine design) and the animated hand was really annoying.
I don't have the GOG version, but hey at least I've bumped it so maybe someone who owns it will come along.
p.s. I don't know why you'd think Windows 95 or 98 would be a good match for the game, it was made in a time when XP was well established.
