The first 270-family GeForce drivers have arrived in the form of the WHQL-certified 270.61 drivers. The new drivers mainly include what we got with the 270.51 beta, including the insane 241-percent to 516-percent performance jumps for GTX 560 Ti and GTX 580 owners when running Dragon Age II with specific high quality settings.
In certain configurations, both cards get a 4-percent to 19-percent improvement in the following games: Mafia 2, Metro 2033, Left 4 Dead 2, H.A.W.X. 2, Civilization V, Far Cry 2, Call of Duty: Black Ops, and Just Cause 2.
The new drivers also include "NVIDIA Update", NVIDIA Update is a feature that will notify you when new drivers are available and direct you to a download location. Kinda like Steam's solution for AMD Radeon-powered users, but, not as good, yet.
