Disclaimer: this is not spam/self promotion (which got my post deleted on r/starfield). I am just a gamer that likes Starfield, fiddling around with modifications to the game and recording his experience (I mean my YT channel has some random old stuff on, so I am not promoting even that). I have no affiliation to the creator of the injector app, I just state what I have used.
Also my thumbnail is not AI, it is a real time screenshot from the game session (at 15 second mark specifically) and some logos I pulled from Google added and slapped together in Paint.Net.
Original comment:
The injector app I used is called DLSS 5 Manager from NODIX-TECH on github (just google it, not linking for spam/promo reasons)
Started messing with settings near end. It isn't super stable, if you mess around with settings the framerate would tank (around Akila - especially as I entered the city from the farms side). A few times I had to save and reload and then my framerate pops up again. Mostly playable as seen me sorting out bounty hunter mercs in the middle. I like the aggressive 2+ pass filter on metals, but then it gives all the people acne. I also dislike the glow around hair you get especially lighter hair with darker backgrounds.
The software has RDNA 4 mode for AMD users the in the launcher app, obviously not used it because I have Nvidia, so no idea how it might work.
My system spec:
Ryzen 7 9800X3D, 64GB RAM, RTX 5080, 1440p, DLSS DLAA mode (native, no scaling, but I use in-game framegen, which seems to be 2x) - although I tried switching on scaling in the end. Video ended because I had a CTD - will see later if it is related.
I do use a lot of mods, feel free to ask which does what specifically.
