This game unfortunately lacks out-of-box support for DLSS which is a performance concern for GeForce owners.
Additionally, the free DLSS mod is only DLSS2 and the DLSS3.5 mod is paywalled.
I combined the Nvidia DLSS 3.5 DLL from TechPowerUp with the Starfield Upscaler Standalone and BaseUpscaler mods into a easy one-click fix with no paywall.
- Download StarfieldDLSS3.5_Mod.exe
- Run and Extract.
- Launch Starfield.
- In the Display Settings menu, simply turn on FSR2
With this mod installed, it will instead enable DLSS3.5
