I'm voting up but I will say this; listing it as a high priority is pretentious. This thing already has been discussed before so many times on this tracker and it will be implemented.

Oh yeah, I totally agree with you that it ruins the world a little, I just want to point out that this has been raised so many times already and that it's not going to change how quickly its going to be adjusted.

This is a matter of tweaking a few values - not really worth as many raised issues as it has.
That said, don't expect GTA level of ragdoll, that used the Euphoria engine which combined AI along with a custom ragdoll engine to create that behavior.

I thought this was a feature to make rolling easier.

I believe this could be an issue with Windows 7 core parking, after boot up the cores are parked leading to poor performance. Using an unparking tool gets the same results. I use this utility (http://www.coderbag.com/Programming-C/Disable-CPU-Core-Parking-Utility) to unpark cores. This feature is meant to dynamically turn on and off to save power, so maxing the sliders is meant to be a little stress test to unpark the cores.
