Played through realMyst recently and, aside from the horizontal/verticle white line problem that some other people have mentioned already, I find that my computer is rendering something wierd when I go to Rime at the end of the game. The odd thing is, the verticle white bar problem doesn't seem to happen here but it's as though the lighting goes haywire as I look around the room. The only think I can equate it to is looking at a 3d model wherein the verticies are not properly welded or surfaces are overlapping (don't know how much that helps people who aren't Game Art Design majors...)
I'm running Vista 64bit. Didn't have this problem at all when I ran it in XP years ago, but then again that was with the CDrom version. Also, I tried the anti-aliasing setting in the setup - that doesn't fix it.

What graphics card and drivers are you running?

Yea more then powerful enough but new cards can still mess up new games. I was more curious if it was an intel onboard chip though which it isn't. What resolution are you running the game at? As a test could you try to run it at 640x480 or 800x600 something low to see if the problem persists with different resolutions that would have been more standard when the game came out.

I am experiencing the same on Rime with the 197.13 drivers, while everyrhing was fine with the 195.62 i was using before, so i'm guessing, at least at my, end it's a drivers issue.
Anyway, any specific reason why you're using the 191.07 ?

Is it outdated? I haven't been keeping up with the drivers I guess. That's what the dxdiag tells me the video card driver is. Guess I should look into updating, then
