Config editing is literally fine in cod runs and is used by pretty much everyone, as in some cases, it’s the only way to cap your FPS. It’s ironic you’re calling Vanilla petty, when you’ve deliberately gone out of your way to go under the cap very slightly, just to try and justify your point. That my friend is pettiness. Cap it to 250 and move on.
if you start shooting the juggernaut right away, it skips the mini slow-mo segment where you cover your face and can't do anything. you should be able to kill him if you just spam with the type-63 at his head, i have an example here, though i missed a few shots:
yeah the newer cods especially have fail-safes to stop you moving too fast into the level, cold war especially has a very broken / glitchy campaign at points. kind of annoying but that’s how they are :( congrats on your sub 2 though!
