I've been trying to figure out why I get bad fps with subnautica and other games. I'm pretty sure it's my cpu. I have an AMD FX 6120, (3.5 ghz boosted to 4.1 ghz.) I got a new motherboard, Gigabyte GA 970 Gaming SLI, and I have an RX 460. If I get an FX 8350, would that help with this? I'm new with all this pc building stuff. I took the cpu out of my pre built HP pc I got like 4 years ago. Everything works fine, just bad fps. GPU activity drops a lot.
