It's simply causes a response delay. You want to shoot something. But the whole screen is screwed up. You will more likely fall off the cliff, fly off the race track. Since you have no idea if your buttons where read at the right point, or miss with the gun. A game requires prescison. Ignoring horrible FPS. If the game keeps changing FPS, it be like trying to jog on a treadmill randomly changing speed. You will get fed up.
