CPU speed limited?

[KillerWolf17]

Whenever I launch Cod MW my computer gets reallllyyyy slow. I checked the clock speed and it said 0.78 ghz and it usually runs at 4.5ghz. This only happens when I play MW and not any other demanding games. Even after I close MW it is still somehow locked to 0.78 ghz until I restart my computer. I googled it and couldnt find a solution so I am asking here.

 

PC Specs:

i7 8700k

1080ti

16gb DDR4 3200mhz cas 14

850w psu

 

all watercooled and never exceeds 60 C

Usually that sounds like a throttling issue due to high temperature. How did you measure that temperature? 

Could be some power saving stuff as well. First clear CMOS then go into settings and disable all C-State and power saving stuff. Also set windows power settings to high performance and make sure standby, hibernation and screensavers are disabled.

The temps were measured using Corsair iCue and MSI afterburner, right now I was playing BFV and it was comfortably hanging out around 50 C.
the power settings are on "Ultimate Performance" The only other people on google who had this problem were people with laptops and solved it with the power setting but im using a desktop.

it is also only utilizing 20% cpu when in MW. This just started happening recently.

 

I will clear the cmos and get back to you

Do you have a MSI motherboard? Are you running their Control Center software? This is causing a lot of problems recently.
