KCD2 Optimisation Help

PLZ help, tech noob here. I’m running the game with i7-10750h, 3060. It was on medium graphics settings based on game recommendation at 15.7fps, before i changed everything to low whereas the game now runs at a whopping 21fps. Also supposedly dlss is supported but the nvidia drive doesn’t even support the game even tho it’s up to date with the latest version.
