I mean that any site ,which are using gameworks features in benchmark are called shills or payed by Nvidia. They even say gimpworks.
Source?
Also the difference between Gameworks and GPUOpen is well... Closed vs Open Source and freely modifiable, and GPUOpen effects tend to have equal performance hit on both sides, vs Gameworks effects impacting Nvidia far less.
980 went from 76 -> 56 fps. 26% perf hit
290 went from 63 -> 36 fps. 43% perf hit.
780 went from 49 -> 36 fps. 26% perf hit.
26% vs 43% in Hairworks at launch.
Lets look at the original TressFX
980 went from 98 -> 69 fps. 29% perf hit.
290 went from 73 -> 49 fps. 32% perf hit.
780 went from 78 -> 51 fps. 34% perf hit.
So 3% faster to 2% slower than AMD using Nvidia hardware, vs 17% slower using hairworks on AMD vs Nvidia.
And thats averages, minimums were destroyed completely.
The R9 290X enjoyed a massive 75% performance jump with HairWorks disabled, making it 17% slower than the GTX 980 -- it all started to make sense then.
We should reiterate that besides disabling HairWorks, all other settings were left at the Ultra preset.

Here is what the Witcher developers CDPR said regarding Hairworks:
Many of you have asked us if AMD Radeon GPUs would be able to run NVIDIA’s HairWorks technology – the answer is yes! However, unsatisfactory performance may be experienced as the code of this feature cannot be optimized for AMD products. Radeon users are encouraged to disable NVIDIA HairWorks if the performance is below expectations."

AMD was able to fix it by forcing it to only render @ 16x tessellation levels not 64x, but there is a major reason why its called Gimpworks.
Also many people here are calling Gaming Evolved Gaming Devolved so its not like its one sided.
