Godrays - The new HairWorks?

As soon as it was announced that Fallout 4 would be using Nvidia's Godray technology many tech enthusiast were instantly annoyed because this technology makes heavy use of hardware tessellation, making it very similar to Nvidia's HairWorks technology that was used in The Witcher 3.

Nvidia are leaders when it comes to the tessellation abilities of their GPU, which makes many people believe that Nvidia have intentionally created graphical technologies like Godrays and HairWorks to specifically harm the competition, as heavily tessellated GPU loads will have a greater impact on AMD hardware. 

Below is a Quote from Bethesda regarding their use of Godrays

 

As always, our world features fully dynamic time of day and weather. To create that volumetric light spilling across the scene (sometimes called “god rays”) we worked with our friends at NVIDIA, who’ve we worked with dating back to Morrowind’s cutting-edge water. The technique used here runs on the GPU and leverages hardware tessellation. It’s beautiful in motion, and it adds atmospheric depth to the irradiated air of the Wasteland. Like all the other features here, we’ve made it work great regardless of your platform.

 

In our testing, which can be seen on the next page, the addition of Godrays is the setting with the largest performance impact in all of Fallout 4's large options menu, so we decided to give you guys the opportunity to see what the graphical difference between Godrays being on and off at ultra settings.

As you can see in the pictures above and below Godrays add visible light shafts and does significantly dull out the games colour. The sky and a large amount of the game world is noticeably different when Godrays are on, but to my eyes I'd personally say that I prefer the brighter colours and greater distance detail that comes from the lack of Nvidia's Godrays, makes me certainly have no problem disabling this highly demanding feature.

Hi

I installed the Nvidia update and went with the recommended settings which were "Ultra" on my GTX 980. I really appreciate your article and photos. I got a couple hours into the game and at 1440P on Ultra it was very smooth for me.

I really am going to go in and make the changes to low quality and turn god rays off eventually. Right now i wish I had a vacation day available to actually play today

Loving it so far

awesome review Mark, lots of info to read up on for those who are not yet playing the game.

it would be awesome if you could add in sli/crossfire scaling for people still rocking older hardware and maybe if you got time to add in i5 vs i7?

only if you got timeQuote

Am I the only one who's not seeing the article/and link in the OP?

Nice write up WYP, although it would be interesting to see some i5 vs i7 comparisons. Someone in a different thread reported a website benchmarking both and there were big differences between them.Quote

It's not there, I've added something to the OP.Quote

I'm finding the performance to be pretty good thus far. I'm getting a steady 60fps pretty much everywhere, with the very occasional drop into the 40's kind of like the way Skyrim was.

That's at 1080p with an i7-6700k and GTX 780 where neither are overclocked.Quote
