Ryzen 7 1700 and GTX 1080 Ti underperforming massively in games

[bgmaokai]

Hello so as the title says my new rig isn't performing as well as i was expecting and i am sure this isn't all it can do.
My 2 problems are in games i get pretty bad stutters and GPU usage drops especially in some areas of the game like for example in Witcher 3 i get around 90-99% GPU usage while running around in the world opposed to the average of 50% in novigrad (on all graphical settings from lowest to highest) this game is only one example of the games i've tried!

My rig:
(OS)Windows 7 x64
(CPU)Ryzen 7 1700 (stock)
(GPU)Gigabyte GeForce GTX 1080 Ti Gaming OC
(MOBO)Gigabyte Aorus X370 gaming 5 (F4 bios)
(RAM)Corsair Vengeance 16GB 2133mhz
(PSU)Cooler Master GX 750W Bronze
(HDD)WD 1TB Green (old model) WD10EZRX
(Case)Cooler Master HAF 912 advanced

All latest gpu and chipset drivers!

My case has pretty good airflow and i don't think i have been overheating,also im runing a clean instalation of windows (completely formating pre-installing and re-aranging HDD 3 times now).
Any help would be GREATLY appreciated, i hope i can fix this already!

Nobody asked if Ryzen "can get you top level gaming performance" (fyi it can).
....

Actually Ryzen falls short for gaming. The benchmarks all show a gap. See:

Overall, the Intel Kaby Lake 7700K CPU at 5GHz Z270 system provided the highest performance while gaming. Didn’t matter if it was single-GPU, multi-GPU, 1080p, or 1440p, or 4K, the most wins (at least in terms of raw data) are with the 7700K at an overclocked 5GHz.

Overall, the AMD Ryzen 7 1700X at an overclocked 4GHz provided the same performance and gameplay experience as the Intel 2600K on Z68 at 4.5GHz. It was most competitive with the 2600K CPU with both overclocked to the highest levels.

In terms of gameplay experience we felt the 2600K and Ryzen CPUs "felt" the same while gaming in single-GPU at any resolution. We "felt" the 7700K at 5GHz had an experience advantage at all resolutions, and especially with multi-GPU CrossFire.

And yet again nobody asked for that.
Go be a fanboy somewhere else.

I have similar problem but my config is;
ryzen 1600 3.8ghz 1.3v
msi mortar b350m last bios
8 gb 3200mhz 4x2
msi rx 480 8gb
evga b3 550w
ssd samsung 860 evo m.2
In practice i see a gpu drops in most games like in the witcher 3 in the city the gpu usage drops to around 85%-90% with a 480! and go back to 99% as soon as i stop moving and the problems persist in many others games but my biggest issue is that i have constant microstuttering.
