So Nvidia have a not yet released driver that they say will give similar performance gains to Mantle but these performances gains, are done in DirectX 11.

Will be interesting to do some game tests and benchmarks tests.NVIDIA shows this another way by also including AMD Mantle. Using the StarSwarm demo, built specifically for Mantle evaluation, NVIDIA’s GTX 780 Ti with progressive driver releases sees a significant shift in relation to AMD. Let’s focus just on D3D11 results – the first AMD R9 290X score and then the successive NVIDIA results. Out the gate, the GTX 780 Ti is faster than the 290X even using the R331 driver. If you move forward to the R334 and the unreleased driver you see improvements of 57% pushing NVIDIA’s card much higher than the R9 290X using DX11.
If you include Mantle in the picture, it improves performance on the R9 290X by 87% - a HUGE amount! That result was able to push the StarSwarm performance past that of the GTX 780 Ti with the R331 and R334 drivers but isn’t enough to stay in front of the upcoming release.
Thief, the latest Mantle-based game release, shows a similar story; an advantage for AMD (using driver version 14.2) over the GTX 780 Ti with R331 and R334, but NVIDIA’s card taking the lead (albeit by a small percentage) with the upcoming driver.
