The Witcher 3: How To Run Hairworks On AMD And Nvidia GPUs Without Crippling Performance

The Witcher 3: Wild Hunt is out now on PC, PS4 and Xbox One. It is one of the few games which utilizes Nvidia Gameworks on PC to add some PC exclusive features. One of these features is Nvidia Hairworks and it seems like there is a trick to run it on AMD GPUs without major performance drops.

This trick was discovered by reddit user FriedBongWater and here is how he described this method.

So thanks to a wonderful user over at Guru3D, it’s been discovered that hairworks can in fact run relatively smoothly on AMD cards. I’m talking 60fps smooth guys, and the trade-off is barely noticeable.

All you need to do is create a profile for witcher3.exe in your Catalyst Control Center, then set Tessellation Mode to “Override application settings”, and finally set the Maximum Tessellation Level to either 2x, 4x, 8x or 16x.

The picture below reveals how to set it up on AMD Catalyst. You can also see the difference between the various Tessellation options in a comparison image.

For the best possible experience, it is recommended to set the Tessellation quality to 4x or 8x depending on your GPU.

If you want to boost the performance even further on Nvidia or AMD GPUs, you can try reducing the anti-aliasing for the Hairworks by using the method listed below.

  • Go to Witcher 3 Install directory on PC.
  • Navigate to The Witcher 3 Wild Hunt\bin\config\base → rendering.ini
  • Search for “HairWorksAALevel” and change it to 2 or 4 for a significant boost.

Hopefully both of these changes can result in better performance for users on AMD and Nvidia GPUs.
