Yes. I mean there is usage but it's similar to the shader based DLSS 1.9.
A little update on Tensor Core usage: I was comparing my overall usage in Control to a different users usage in Wolfenstein. However it seems like that user zoomed in the last part of the frame where the tensor cores are heavily used, resulting in a much higher overall usage. That's where the 1.9% versus 60% come from.
So yesterday I captured Wolfenstein on my device, thanks to the new Nsight version, Wolfenstein wasn't blocked anymore like before. I observed overall usage to be similar to Control, so yes those Tensor Cores are used and I assume needed to provide this huge boost in image quality!
What's strange is that I could swear I also had captured Control before the patch and drivers, and the usage was very similar to what it is now. It could mean the shader version, DLSS 1.9, was running on or atleast supported by the tensor cores.
Pretty interesting stuff. Sadly I don't have any captures of the old Control DLSS anymore, so I'm just going by memory here. Could be false, so don't take it as a fact!
Just felt the need to clarify that, I don't want to spread misinformation.
Has anyone tried this with just 1080 output and DLSS @ 720? Would it be worth it?
Yes. Even the lower settings do look great imo.
