Failed flat as a theory when using the Win10 driver on Win8.1.
You aren't reading the computerbase article closely enough.
"H has now also carried out a benchmark run under Windows 10 to the latest Windows Update by partly filled with Catalyst drivers for the not yet released operating system.
And lo and behold: Project Cars running faster. Even when compared with the same driver under Windows 8.1, the performance increases depending on the scenario by ten to 13 percent."

That means with the same driver, the performance still goes up switching from W8.1 to W10. W10's purpose was to reduce CPU overhead in games. The performance increase by just switching from W8.1 to 10 for R9 290X with the same driver is almost the same as moving from an FX8370 to an i7 4770K when using a GTX980.
Also, way to ignore all the other information/data in this thread re: PhysX.
LOL @ this poll and it's results.
Very clearly shows why I don't bother with this forum. It's full of fkin idiots.
Maybe you might want to try reading the entire thread before throwing accusations. If you have alternative explanations that make sense, please feel free to provide them and everyone will listen as long as they are logical. Alternatively, if you don't want to learn about how PhysX works on GPUs and why using PhysX on a GPU for 1 AIB for car physics engine is a distinct and unfair competitive advantage, because this methodology forces Intel/AMD GPU users to run the same calculations on the CPU, then go right ahead and make an account at ABT. They will love you over there. If ProjectCARS had some On/Off switch for certain aspects of PhysX, it would have been acceptable but to make the core physics engine based on PhysX is gross ignorance and disrespect to all PC gamers who do not own an NV gaming card. Calling people idiots isn't going to get you anywhere.
so blame the dev? seems logical to me.
Let's get one thing straight: the developer is way more to blame than NV here since the developer has the power to make game engine decisions that shape the entire game. However, once the developer decided to implement PhysX for the physics engine, it was NV that partnered with SMS and started marketing the game. Whatever a corporation does today sends a signal about what they stand for. Stating oh well, NV had nothing to do with it, the developer screwed the entire game, dismisses that corporations have a public image and whatever partnerships NV/AMD engage in, it is their corporate image that stands complementary with the end product, does it not?
When AMD openly goes out and publicly states that they have shared all the source code with Nvidia or anyone and any of that code can be optimized, but NV remains mum and pretends like who cares, what does that tell you?
Does it look to you like the developer just did all the work on PhysX on his own with 0 help from NV?
Did you not realize what the topic of the thread is? Did AMD ever side with a developer and helped them include a proprietary closed source code that could ONLY be run on AMD's GPUs but forced Intel/NV GPUs to run it on the CPU?
Yes or No?
Did AMD ever work with a developer to provide proprietary closed source GPU code that directly favoured their GPU architectures and that code could never be optimized, altered or modified by NV/Intel?
Yes or No?
Dude, NV is literally putting its face/brand logo with a game that from the get go was designed to alienate Intel/AMD PC gamers. Do you know of any game made on this planet that was made from day 1 knowing all Intel/AMD GPU setups would be at a distinct disadvantage because of its inherent design? What happens when a person with an Intel APU in 4-5 years decided to play this game and get 2-3X less performance than an NV GPU of a similar level of performance? Too bad, I guess?
It doesn't get much obvious than this. I guess you are OK with such business practices because you only buy NV GPUs, so who cares, right? Millions of other PC gamers worldwide with Intel and AMD GPUs - who cares about them - it's their fault for not buying NV, right?! I guess we should all just not care and buy NV and let the PC gaming industry become a monopoly = $550 mid-range GPUs, $1000 flagships. Go Premiums!
