I found out that the setting causing laggy and bumpy framerate is "Enviromental detail" (the only one that needs the game restart to apply) , other settings don't rly affect fps (except maybe new ones like Dynamic Character resolution and Global Illumination). They fced it up after 4.0 update, before that my game was buttery smooth. So you just need to lower Enviromental detail to High (still would have some unpleasant microlags sometimes), or even to Medium. People are also saying that Genshin recompiles shaders ingame now, so after each patch game becomes more laggy.

@@princessochka3690 Are many other people experiencing heavy lag in the game? I hope it will be fixed in the future to make the game smooth again like it used to be. (Before my game was very smooth.)

@@MREKK-uk3qp It isn't really a hardware issue, my CPU/GPU have 30%/50% load at all times. It is something about their engine and how it renders objects. I heard people with higher GPUs expirienced same issues, but i think the majority of players have lower-end PCs and play on medium settings. It is like that for 8 months already, and Mihoyo are known for not doing anything about their game. I doubt they will fix it. If anything, i expect lags to become worse after Nathlan release.

@@princessochka3690 We can only wait. This game has beautiful graphics and pleasant music. I miss playing when it was smooth without many issues.
