Have had this issue for awhile. For some reason I can enable Ray Tracing, but the option for DLSS is grayed out. I have uninstalled and reinstalled my drivers several times, I even recently did a clean install of windows when i got a replacement 2080 TI sent to me by EVGA and i'm still having this issue. Any suggestions? Running Windows 10 64 bit, Direct-X 12.

I haven't had this issue myself so I can't speak from any personal experience, but I found some things online when DLSS was greyed out:

- Verifying DX12 is installed. Type dxdiag in the Windows search box.
- Rolling back GPU driver to an earlier version.
- Installing Geforce Experience.
- Do a CLEAN reinstall of the GPU driver using Display Driver Uninstaller (DDU).
- Reducing game resolution to 1080p.
- Manually updating the DLSS driver (nvngx_dlss.dll). File located in [X]:\Cyberpunk 2077\bin\x64

Personal recommendation especially when on a 20xx-series card is leaving both RayTracing and DLSS disabled.
I got a RTX 3080 card and that's what I'm doing. RT makes the lighting fancier, but to counter the FPS impact with DLSS, everything else looks worse.
