Also make sure to check full screen anti-aliasing option...
I just looked at setup again, and my option for anti-aliasing is greyed out (unchecked). This install is on my laptop, which doesn't have a great graphics card. Maybe if I installed it on my desktop, that option would be available.
The game, by default, did put my Texture Quality to High, though.
Also, under the Advanced tab, it has an option for DirectSound3D. Do you recommend ticking that?
EDIT: I've been spending a little time in realMyst and came out of a building. It had turned night! I forgot that it did that in this version. Took me by surprise. I'll have to do the indoor puzzles during the night.
Oh, and BTW: I looked into using DirectSound3D and apparently Vista, Win7, and Win8 do not support this option unless the hardware can use a special driver, such as OpenAL. Since I'm just playing on my laptop, I'm not going to worry about that setting. Hopefully, I'll be able to hear all the atmospheric sounds in the game.
