3D Pinball was originally written for Windows 95 and had a render loop that  painted frames as fast as possible. But it was found while porting it to Windows XP that Pinball’s frame rate on contemporary hardware (then) was over one million frames per second. Microsoft later added a limiter in Windows XP, that capped the frame rate to 120 frames per second. This was enough to drop the CPU usage from 100% to 1%. While porting several millions of lines of code from 32-bit to 64-bit Windows, one program that ran into trouble was Pinball. While one could always add Pinball to subsequent Windows versions, it was not recommended. Windows 8 users can now check out Pinball FX2 game, and let us know how you think it compares with the original Pinball game. There are other Pinball game apps for Windows 10 available as well.
