Games that use older versions of DirectX also are affected.
And... this would be a bug affecting every system with optimus?
Yes, it seems to affect every laptop with Optimus: http://nvidia.custhelp.com/app/answers/detail/a_id/3733 It also seems that nVidia won't (or can't) fix it.
Thanks for the link, I've added this issue to the page now.
This might simply be the result of a different GPU scaling option being used. I've suggested that possibility in the forum topic.
Houston, we now have a solid explanation (which can be further understood by reading this)
EDIT: I don't really know what I was thinking. Anyhow, it's probably nvidia and whatnot switching their driver to the "harmonized" api microsoft gave them (instead of whatever hack they were doing with older WDDM/Windows).
