Here is a review by HarewareCanucks....I find the last paragraph interesting.  Hopefully LM will be

working with Nvidia on a P3D API.

"All in all NVIDIA’s 337.50 beta driver is an extremely impressive step forward in terms of performance. While it won’t noticeably benefit every game at every detail setting, the framerate increases have been accomplished without moving to a vendor-specific API. By simply reducing latent driver overhead NVIDIA has empowered developers by deftly avoiding the complications associated with programming Mantle into a game engine. That makes PC game development much simpler and substantially more cost effective. While DX12 will likely boast similar improvements (and then some), it is still more than a year away. Having access to these benefits right now through a simple driver rollout is invaluable for gamers and the gaming industry as a whole."

It has been there a while, it came out little after the 337.50:

There hasn't been much fuss about this hotfix release as it just fixes few fatal bugs with Hyper-V and some Dell display not working properly with the 337.50 driver. Other than those fixes, this driver is exactly the same as 337.50 so it is obvious that it performs the same.
