I'm considering upgrading my pc to get some better performance in game. I'd like to hear from people who have some more powerful hardware, is the situation any better for them. Right now I have i5 4690 and gtx970, and on ultra settings sometimes i have smooth 60fps, other times it drops below 30. Reducing graphic quality helps very little when fps drops, like when there are more trains around etc. So, my question is, can I expect a significant improvement from switching to something like i5 8600, or even some newer i7? What is the performance like for people who already have those cpu's? I doubt my gpu is the bottleneck here, but would like to hear opinions and experiences on that too.
