I'm still using 195.62 drivers and I'm wondering if there are any problems with the 257.21's and if I should get them. I noticed I've had this strange problem with The Sims 3 lately. I would play for a long time and have no problem but other times I play, I'll play for 30 minutes and then the frame rates drop from a steady 85-170 to a very low 9 FPS. Don't know why. Nothing intense goes on just reading books or napping. Could it just be a Nvidia driver issue solved in a newer driver since mine is kinda old?
