Game runs too fast on my Windows 7 64 bit Intel i5-2500k machine. Is it a way to set the game to its standart speed?

If you right click on the shortcut/executable for DD and select Properties, then switch to the Compatibility tab, does changing anything there help?

You could try using the disk version configuration program to switch the game to software mode, rather than Direct3D, and see if that make a noticeable difference. There is a link to download the 'Old DD Config Tool' in this post.

You could set the game to run on a single CPU core, or run a program like cpugrab in the background (cutscene issues).

Got game running properly, now it may be too fast!
