Nvidia's parternship with Ubisoft did nothing to improve experience in the game, and did nothing to show Ubisoft gives a crap about PC.
On the contrary, AC IV has significant PC enhancements including 4K support, TXAA, PhysX, HBAO+, PCSS etcetera..
Watch Dogs has 4K support, and ultra level detail which is much greater than what you find on the console versions and looks a lot better.. It's a shame that the engine has so many issues with resource management on the PC, as the game can look beautiful at times..
They purposely gimp the game to make consoles look good. They release patches when they feel like it. DX11 multithreading did pretty much nothing to benefit the game, as Nvidia and AMD are neck and neck in performance. TXAA looks like the same old smeared crap that it always has.
I don't think the game was purposely gimped. I think the engine has a lot of performance issues and they cut some features or didn't fully implement them due to lack of time. Also DX11 multithreading does help, in CPU limited situations as shown by pcgameshardware.de's CPU and driver overhead benchmark.

The only benefit TW3 has going for it is PhysX, because I think CDPR will make good use of it, and not waste it on the stupidity of billions unrealistic particles.
I'm surprised a rabid anti NVidia guy like you would think PhysX a benefit in the Witcher 3
