Gaming Performance?

To what extent can the monitor affect the apparent frame rate of a game? When I play Superbike 2000 on one monitor, my frame rates seem reasonable. When I play on another monitor, the game runs like, quote “A dog!” Could the monitor be expected to affect gaming performance to this extent? There is nothing wrong with the monitor otherwise.

I doubt it has anything to do with the monitor.
What kind of graphics card are u using ??
I would look in at my graphics card first before I blame my monitor.
