help please!

Ive been playing scream machines and i have noticed that the game tends to skip ahead to certain points on the track whilst riding them. also in copter mode i move crazy fast sometimes and go way past where i was going... is there any way to fix this problem?

Have you updated your video drivers? Sounds like that would be the cause of the problems.

yea but i dont see how the game would just change speed randomly... it dosent happen when i first start it up just after editing for a while
