DLSS vanishing and poor DX12 performance

Hello,

i wanted to know if its known that dlss randomly stops working and disappears from the settings? I originally was in DX12 then switched back to DX11 and it reappeared but then it vanished again in DX11.
I also rolled back my Nvidia driver from 572.83 back to 566.36, dlss was again available in DX12 but later vanished again. Is a fix being worked on?

For DX12 poor performance i noticed that i couldn’t break past 100fps on my 4080. When i looked at its usage ir didn’t go past 40%, it was so low that the gpu started to down clock it self (like going from 3d mode back to 2d mode). In DX11 i get full gpu usage and get almost 300fps. I know that DX12 is in beta but also there, are there any performance improvements being worked on for DX12?

Thanks

Open your config.blk, go to video and change it manually to dx12, save then set your config.blk to read only. Then when in game you can un-set it from read only to change settings and when done, change it back to read only. That way your settings won’t be reset.

But in my experience dx 12 sucks. It doesn’t perform as well and is more unstable than dx 11. And while dx 11 doesn’t support ray tracing, that itself is too much of a performance impact to be worthwhile.

Alright, i’ll try that thanks
