Possible CPU bottleneck?

[DevilsKnock𝄡]

So I have I7-4790k 4.4 ghz, GTX 1080, 16 GB RAM and Win 10. I've been looking at my computer's usage quite a bit for this game lately and my GPU usage will stay upwards of 80-90% if my CPU is around 40-45% usage but when my CPU hits around 50% usage, my framerate just tanks along with the GPU dropping down to around 50% usage as well. My guess is it is a bottle neck but was wondering if anybody else experiences something similar in the I7 series with hyperthreading (which I'm guessing this game doesn't use like most don't). I get it's a CPU intensive game but that's some pretty large framerate drop in just a 20vs20 match (unit size is ultra).

Edit: Well, did some more testing and I have no idea what the hell is going on in these battles. My CPU will always stay somewhere between 40-50% in these 20v20 but my GPU is all over the place. If I look away from the main battle, my framerate goes up to around 70 as it should and my GPU usage goes to around 80-90% again, CPU still stays the same. If I even attempt to watch the battle, I get a cinematic 20-30 fps but my CPU barely changes at all from before but my GPU drops it's usage by about 50%. The moment I look away from the battle, my GPU will be used again. It's like it's throttling itself for the one thing I actually care about. I'm pretty damn confused. It's not that it can't push itself, it goes up to 90% easily if I look away, but for battles it just won't.

why do you even bother putting this on discussions.
You're going to get the same spastics who think they know everything about the world and how everything works, just turn down settings or something.
