Not sure, but i think Leslie is asking if you have a later version.
Version 8.17.12.8562 equates to what is known as 285.62 (extract digits).
So you could upgrade quite a bit. 296.10 i find is the best yet. One thing that does annoy me while updating drivers - the desktop icon locations get messed up or missing altogether. So i always use a desktop save utility to save desktops before any nvidia update. Then restore when done.
