--------------- Possible issue #1 ---------------
Device Name: Razer BlackWidow Chroma
Attached: 1
Event Name: APPCRASH
Problem signature:
P1: RzSDKService.exe
It’s very common for the Razer SDK to cause low fps and even game crashes. These are addressed in the sticky threads here:
--------------- Possible issue #2 ---------------
Problem signature:
P1: audiodg.exe
Problem signature:
P1: NvSHIM.exe
P4: NahimicOSD.dll
Another common issue is with Nahimic audio software. There is an error for your audio drivers crashing, and also an error for Nahimic crashing. These can also cause fps loss as Windows needs to continually reboot them in the background. For more information about disabling this, see this post:
--------------- Possible issue #3 ---------------
Problem signature:
P1: ArmourySwAgent.exe
Problem signature:
P1: RefreshRateService.exe
These are two of your built-in tools from ASUS/ROG crashing. I don’t know if they are related to your time in Overwatch, but you could try disabling them at start up and seeing if the issue improves.
Best of luck. I’m still tracking this thread. Let us know if anything here helps in case someone stumbles across your thread in the future.
