Not sure what it is that you are asking here.. Forceware drivers are what you call "stock" Nvidia drivers. They are created by Nvidia and not 3'rd party's.
Edit:
eh, I see you are talking about the beta drivers. Naturaly as with anything else there is a possibility for problems.
Edit again:
Hmmmmm Are you talking about beta drivers? As the current ones are 71.84. So i ask you if you are not could you please provide this info in your post? the more information you share with us the better the answer we can provide for you. thank you.
