The free DLSS 3.5 Starfield mod works perfectly. There's only one big glitch in which you get a small stutter when zooming in with a sniper rifle.. and there's a little ghosting on some elements of the UI otherwise seems to work fine and essentially double fps. Not sure if Reflex is enabled with it but input lag seems decent. Which is great considering how poor it runs on most hardware. Also f that guy who tried monetising his mod with DRM lol.
Hardware Unboxed did a massive CPU comparison in that game and looks to be a very demanding on AMD CPU's. Even Zen 3 struggles in the game. Sad state of affairs in gaming when even processors from a couple years ago offer such performance. Granted Steve was using a 4090 at 1080P still Creation Engine continues to be a dinosaur.
