Maybe.
I only skimmed the article but it doesn't say HOW it was tested; what hardware, what settings or anything else.
It is highly possible that they have gone in, made the game run on a small number of threads and then burnt a shed load of time on other cores to push this work off the gaming thread - does it help frame rates and score headlines? Sure. Does it solve the problem which is a fundamental issue with the way the DX runtime is structured? No.
More importantly until it has WIDE testing we don't know how much of this are game specific hacks/optimisations to make things look better. It could be window dressing for a few big games which means that unless your game is blessed by NVs Driver Team it won't see these gains.
While interesting for me there are too many unknowns right now to say what they are doing and how good it is - show me the raw data on low end systems and then we'll talk, but if they are burning cycles on a high end one to put Mantle in the shade then No Deal.
