Originally posted by Heisenberg:I had similar problems, this is what fixed it for me (Windows 7 pro 64 bit):Right click on C:\Program Files (x86)\Steam\SteamApps\common\Real Myst, go to Compatability tab, and check the box to run in compatability mode for Windows XP (Service Pack 3). I also clicked the box to disable desktop composition, but this is probably not necessary.In the same directory, double click on realMYSTSetup to run setup. Select first video option without T&L (I use NVidia GeForce GTX 670 Direct3D HAL). Set screen resolution, texture quality and anti-aliasing as you like. I have them set to max values with no problem.
