@Arc Man this has been reported several times already. What is going on?
Also, adding to what @MarksmanMax said, i've seen the small ammo boxes on cap vanish after it is successfully capped, and this also affects HC mode.
And did you know that the weapon retraction system gets you killed alot in Frenzy? They run close to you, and your character lowers the gun...

This is the reason you're having bad performance. You're already saying it: GPU usage low, CPU usage all over the place. Your CPU isn't fast enough to feed your GPU properly in this game.
Unfortunately, your upgrade options are somewhat limited. You could upgrade to an i7-6700k which is the least expensive option to a 4 cores / 8 threads CPU for your socket, but compared to currently available CPU's it is actually very expensive, but still a proper CPU in games. You might also have to upgrade your cooling solution though, depending on what you have currently.
But before you upgrade or buy an entirely new system, try some tweaks. Maybe those will help.

The reason i'm posting several things in here is because, yes, as well as with this bug right here, alot has been reported already but not fixed. I'd even argue that all the bugs and issues should be known, because all of them have been reported. So this was just a small reminder, because at times it feels like the bugfixing is really slow.
Anyway, had this bug happen again just now.
In an attempt to make the unlocking via levels a bit more interesting, i bought all the 100 and alot of the 200 token clothing a while ago so i could unlock some cooler gear by leveling.
Since then however, i've noticed on two occasions that the game is still handing out stuff i already bought or unlocked. I just unlocked "Loose Fit Black - Red A", a 100 token head scarf, which i definately bought a week or two ago.
While i personally don't much care for achievements, visual unlocks and the like: now that it is in there, i find it frustrating that it doesn't work properly (yes, that is the psycho effect you added by integrating this "shop" and it's why i usually despise this kind of thing).
And while i'm at it, please remove the team damage reflection which has been asked countless times by now, and also the weapon retraction mechanic when encountering other players or npcs in very close quarters, thanks.
I believe this issue has been posted before but for the normal game modes:
If a character stands right in front of you your gun will automatically be retracted. This is particularly annoying in the Frenzy gamemode where zombies try to get near you all the time. I've had countless situations where i was not able to shoot and subsequently died because the weapon was retracted because of this mechanic.
