On epic settings in 1080p should be 90 -120 fps, at 1440p 65-75 fps, well, in 4k 30 fps +-. I repeat, this is epic and the processor is more powerful than yours (Ryzen 7 5800X). In your case, maybe a little less. If you do not limit the video card (do not include vertical synchronization), then it should work at 99% in directx 12, preferably. And one more thing, the built-in indicators in P.O. amd adrenaline, they lie about the load on the video card and show incorrect data, in fact your video card can work at full capacity, but it shows a load of 80 +- % and these readings change quickly, even if you look at one point, and it shouldn't be like that. In msi afterburner, there is a check mark in the settings to enable the universal GPU load monitoring mode, and in this case, msi afterburner will correctly monitor the load of the video card during the game. In your case, look at the frequency and consumption of the video card in watts in amd adrenaline, somewhere around 160 watts is the maximum consumption of the video card at maximum load.
