Why does the simulation of the game [Solitaire] in Windows 2000, which appears after the game is completed successfully, execute more slowly as compared to Windows95 and Windows98?

The difference in the simulation speed is due to the different specifications between [Solitaire] of Windows95/98 and Windows 2000.

When the game was first included in Windows, the simulation after the successful completion of [Solitaire] showed the slow falling down of cards on the screen in 1-2 minutes. In parallel with the evolution of the processing speed of computers, the falling down speed of cards becomes faster gradually such that the simulation ends in a few seconds. To reflect the original design of the game, the simulation of [Solitaire] in Windows 2000 has been modified to show the falling down of cards slowly in 1-2 minutes.
