Everything on my pc doesn't run full usage. WHY?

[romanz7531]

So I play any game on steam and Im stuck with 30% gpu usage and 30% CPU usage on all CPUs.

I have Ultimate Performance enabled in power plan, and my gpu is overclocked, and I do have performance mode on Nvidia's power plan.

Here is my benchmarks and images.

My specs:
System Dell Precision WorkStation T7500
Motherboard Dell 0D881F
Memory 22.8 GB free of 32 GB @ 1.1 GHz
Display 1920 x 1080 - 32 Bit colors
OS Windows 10
GPU PNY GTX 1080 Ti - Core Clock +150 - Memory Clock +650
CPU Intel Xeon x5675 1 CPU, 6 cores, 12 threads Base clock 3.05 GHz, turbo 3.2 GHz (avg)


I'd like to mention I tried to go to a bios, but all I get is System Setup because my motherboard doesn't have a UEFI Bios. So I cannot overclock CPUs

Are any cpu cores at 100%?

Are you using V-Sync or any FPS limiter?

No I'm not, just playing games regularly with no vsync on

And cpu core usage?

What FPS are you getting?

It tells you the core usage in the Imgur, and the CPU is the same exactly as the gpu usage. Also im getting like really shitty fps at the 30s-40s
