Call of Duty is the only game that does this on my console. Not one single other game or app does this, just exclusively Call of Duty. Playing on a Series S with COD installed to the internal SSD for the fastest read/write speeds. I have fully Uninstalled and reinstalled the game three times to attempt to remedy this, but it never works. There is no warning this will happen and no rhyme or reason I can find for it to do this.
I feel like it cannot be a console/SSD issue because much more demanding games I play absolutely flow with ease. Also no, it is not internet related because once again, COD has been the only game to do this, period. And when I have system diagnostics running on screen there are no drops, dips, or hanging that appears in the data.
