When I play call of duty ww2 multiplayer, only about 30% of the gpu is used (gtx 1070) and only about 40% of the cpu is used (i7 6820hk). This is with the game running at 1080p at low settings. I average about 80-110 fps. I play on a 144 hz monitor, so it would be nice to be able to reach the full potential of the monitor. Does anyone else play call of duty ww2 with the evga sc 17 1070? The fps I average seems low to me. No matter what I do I can't seem to break 110 fps. How can I get the game to fully utilize my hardware? 

Yes I do. 

My cpu gets pretty hot at 70-85 C, my gpu stays relatively cool at about 60-65 C.

No im not running any frame limiting software. I get the same fps even when just using fraps or using the built in steam fps counter. 

Ok, I got 394.4 with those settings. 

I already did all those except for the kboost. My fps remained the same or increased only slightly with kboost. Do you happen to know other heaven scores with evga sc 17 1070s? With kboost, rivatuner says that my gpu usage is 0% but that obviously can't be right. My cpu usage went slightly up. 

You are playing the game in full screen mode correct? Have you ever optimized the game with geforce experience?

Lets try an older driver... http://www.nvidia.com/con...g=us&type=geforcem
 
Note: Clean out your current gpu drivers using DDU before installing the older driver.

I'm thinking the issue is game related. It sounds like the game is only utilizing 2 of your 4 cores for some reason.

If you get the same fps with your external monitor disconnected I would try the following...
 
#1 Reinstall windows. You said you were planning on doing it in your other thread.
#2 Update to the latest bios & make sure the bios is set to default settings afterwards.
 
If your problem persists after doing those two things it's definitely a game issue.
