I think you're gonna need a GPU. I'm not a hardware expert but I do know that this is a GPU heavy game, not a CPU heavy game. I get about 100-125fps out in the world and about 60fps in my larger bases. in my huge creative builds it can get down to like 40. Pretty good and i'm only running a Ryzen 5 1600 with a 1060 6gb. So you don't need to spend too much but you do need a dedicated GPU. the GPU shortage is over as hell so you should take advantage.
