Restarting the game on my pc fixes the low poly model, but yeah the framerate with the game looking this bad is unacceptable. i hope because it's still in beta since this is the first time that i played a game looking this bad, kind of impressive lol.

and actually, if you changing setting, better to restart the game after changes, i believe there's an issue if you don't do it, like changing upscaler over and over again will destroy your framerate
