How is the dogshit performance not a priority for the devs?

I was playing the game pre graphic update on a 5600x and 1060 at easily 100fps with low 80s on some maps. Now post update, with a 2060 (instead of a 1060) I am getting 40-60fps with severe stuttering on some maps. Ive been reading threads where people with 3060tis are “happy” to get 40/60fps. Wtf happened in the update and how is OWI this incompetent? The game literally looks the same graphically and cant even begin to comprehend what the fuck they did the butcher their game this much. I literally got better performance on a i5-7600 and 750ti back in 2017. Rant over thanks in advance :)
