That said, I think AMD's Gaming Evolved program leaves much to be desired. The graphics effects like CHS are second rate compared to what you find with NVidia's Gameworks..
Deus Ex Mankind Divided would have been a better looking game, and probably even a better performing game had it been a GW title rather than a GE title.
AMD Gaming Evolved titles are much better than Nvidia Gameworks titles in terms of stability and performance at launch. They are also very well reviewed.The majority of Nvidia Gameworks title we have seen are basically terribly broken and unoptimized at launch. It takes months for the developer to get a Gameworks title to even run properly on GPUs from both vendors. Few games like Witcher 3 Wild Hunt had pathetic performance due to Hairworks and then the developer introduced a tesselation preset - "High" and "Low" and another option which implemented Hairworks only on Geralt or all characters. This patch was introduced 3 months from launch after there was a lot of criticism on the performance hit due to Hairworks on not just AMD GPUs but older Nvidia GPUs like Kepler.

The GameWorks HairWorks Controversy
There was however one particular controversy that sprouted up specifically around the game's usage of NVIDIA's GameWorks featured called HairWorks. First let's just list all the webpages you can visit yourself to read about the issues and draw your own conclusions from that. Then we will briefly talk about it on this page, and go into more depth in the conclusion based on the testing we found.
You can read about these issues: [Here], [Here], [Here], [Here], [Here] and [Here].
When the game was originally released there were reports of very slow performance, especially when HairWorks was enabled. What's more, there seemed to be odd performance behavior between last generation GPUs, current generation GPUs, and AMD GPUs that didn't make a lot of sense to many people.
The Start
The controversy started when Marcin Momot at CD Projekt RED posted that performance optimizations of HairWorks for AMD GPUs could not be made. Here is a link to the post, and the full quote below:
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. Hope this information helps.
Tessellation Factors
From there, allegations were made that HairWorks was rendering way more Tessellation factors than what is actually needed to allow the visual differences experienced in this game. The controversy alleged that this was done so that past generation GPUs would not perform well with HairWorks, thus creating a need to upgrade to new generation GPUs that handled Tessellation better. This also translated into worse performance on AMD GPUs that struggle with high tessellation factors versus current generation NVIDIA Maxwell series GPUs.
GameWorks
This sparked a wide array of debate across the Internet about the validity of GameWorks features in games and how GameWorks could be used to alter performance in a manipulative way. There are certainly proponents of GameWorks features, and there are those that oppose the graphical effects based on the potential for performance manipulation from poor business practices.
Patch Improvements
To address concerns about NVIDIA HairWorks performance, CD Projekt RED released a new patch version 1.03 and 1.04 that specifically improved HairWorks performance.
It wasn't however until patch 1.07 that finally improved NVIDIA HairWorks options in the game in a big way. With patch 1.07 gamer's were given more control over HairWorks performance features. With the new patch 1.7.0 gamers could now select the AA level, from no AA to 2X, 4X and 8X AA applied to HairWorks. In addition, the patch added the ability to select a lower quality HairWorks setting that alleviated many of the performance concerns the high quality mode demanded. The gamer also has the ability to select HairWorks "On" for HairWorks on all things, or just "Geralt" for HairWorks just running on the main character.
With all three of these options HairWorks can now be tweaked, and less demanding options can be used while still running HairWorks. This so far has seemed to satisfy most. Since then, newer patches have come out as well, such as patch 1.08 and then a hotfix 1.08.1 and 1.08.2.
Now that the game has been out a few months, and there have been many patches released, we can finally bring you our full evaluation of gameplay performance and IQ. We can finally see, after all of these patches, how AMD and NVIDIA GPUs really compare in this game with and without HairWorks.
We are using the latest patch 1.08.2 for all testing and the latest video card drivers.
And here you are claiming Deus Ex MD would have been a better title if it had been a Gameworks title. What a joke.
