Hey Jon.
Can you post graphical settings. Latest nvidia driver number. And then download AMD Ryzen Master.
Check your power to cpu is at least 1.134 volts or higher. Mines 1.3 cause I OC my 2600 to 4.1 ghz.
Check to see if you can overclock your GPU too. If it doesn’t boost your performance try fresh installing.
I know that’s a pain but cod is a hard power consumer. And if your volts off read you’re not getting the right power to those parts which can in turn cause bottlenecks and bad performance.
