[SOLVED] GTX 1080 only running at 50% in Overwatch causing insane stuttering

[swenson.tor]

So my 1080 just came in and i was looking forward to using it. turns out that overwatch is a steaming sack of shit and only wants to use 50% of my card so I get massive framedrops and stuttering at 1080p. Game is unplayable and it seems that reinstalling my drivers made it worse. I've done everything in my power to fix it and nothing seems to work. I saw something on the forums about disabling HPET but apparently on ASUS boards you can't change it, and when I tried doing it in command prompt it didn't seem to change anything. I've tried all different settings etc so if anyone else has other solutions it would be nice.

My specs if you're wondering:
Intel i7 7700K Overclocked to 4.8 GHZ

16 gigs of tridentz ram clocked at 3000 mhz

Cooler master masterliquid 240 lite cooler

Asus z170K motherboard

Remove GPU, boot to safe mode and use DDU to remove all nvidia and AMD graphics drivers. Shut down, install 1080, boot up, download latest driver from nvidia.

CPU never goes above 80% usage and never goes above 80 degrees Celsius. PSU is Seasonic 620Watt 80+bronze.

Ok I will try that now.
