8500gt driver help


In Runtime
A couple of games I try to start up the videos are choppy and lag really bad...I'm using 169.25 at the moment, are there any newer ones out there? that one was the highest I seen on the nvidia site for vista 32...or should I just use the XP drivers?

or could the lag in the vids be from some other out of date driver...is there a program that can let you check for out of date drivers?
