In our investigation we found that across a sample of Tessellation heavy games and benchmarks that the AMD Radeon R9 285 was either ahead of the Nvidia GeForce GTX 960 or at most 13% behind. Seeing as how Tessellation x32 is what’s used for HairWorks we were anticipating a similar 13% delta between the R9 285 and GTX 960.
But what we have found with HairWorks is that the performance cost on the R9 285 is double that of the Nvidia GPUs and it’s nearly three times for the R9 290X. If AMD’s tessellation performance was the real reason behind this huge penalty running HairWorks as Nvidia claims, then we would would’ve seen it reflected in our other tessellation tests but that’s clearly not what we’re seeing.
A 13% delta between the R9 285 and GTX 960 turns into a whopping 206% delta, in both instances running tessellation x32. The main difference is that in the first instance both cards were running a standard piece of code that both companies can optimize while in the second instance the R9 285 is running code developed by Nvidia that AMD cannot even see.

Virtual reality is the next frontier of gaming and 3D intensive applications, and NVIDIA is helping to pave the way with GameWorks VR. GameWorks VR is NVIDIA’s set of APIs, libraries, and features that enable both VR headset and game developers to deliver amazing VR experiences.
