As I said before, not every map seems to be affected. There are also some people reporting issues with maps, in different play modes.
Argonne Forest was running better before the latest patch. There is constant stuttering now, like it's never running really smooth.
Maybe it's the framepacing?
Even my girlfriend noticed it, and she didn't even knew about the new patch.
Argonne Forest maybe had little hiccups here and there pre-patch, but it was never like this on my Pro. I remember how i noticed, how much smoother it was running, when playing on my Pro. Looked like perfect 60fps at times. And now it feels very different.
