Ok, we're talking past each other a bit.
You'd originally asked if other people were seeing the same thing. As I indicated, at default sliders, I'm not.
It feels like the next logical question would be what's different...what's causing some people to experience what you're describing, and others not. The first answer that pops up is "other slider settings". That's not the only possible answer, just the first most likely one to investigate.
Whether what you're observing is animation-driven or not feels like it's beside the point....the issue isn't that the throw out of sack animation exists, the issue is that you're seeing it successfully avoid a sack at a higher rate than other people.
If the animation itself were just fundamentally broken, we'd all be seeing the behavior you describe. We're not.
You're not even seeing it consistently....you're only really seeing it when the CPU rushes you as a user.
That speaks to something more localized to your setup, playstyle....something.
Shrug. Good luck tracking it down.
