One early videogame that got this right was Alley Cat... in '83!
The x86 version, coded in assembly language, works at the right speed regardless of CPU speed. MobyGames has this to say [1]:
> "Alley Cat was one of the few games of the 1980s that was programmed with full attention to different PC speeds. It's an early, old game--yet it runs perfectly on any machine. The reason it runs on any computer today is, upon loading, the first thing it performs is a mathematical routine to determine the speed of your processor, and as of 2003 we've yet to build an Intel PC too fast to play it."
I had a lot of fun with this game back in the day, when I got my first PC, an XT clone (with Hercules graphics card and "amber" monochrome CRT!).
