Downloading now, I explicitely want to test ragdoll physics and check if things have improved in terms of stability there.
I hope for no more odd constraint violoations flipflaps, maybe a self-trap check for constraints. More stable simulations on irregular frametimes, as a user before me noted, a better simulation when time dliation is present, better performance when several complex ragdolls are active, aaand so on.
Edit: Ok tested it very briefly by simply porting one of my ragdolls over and doing some simulations in the phat editor and the main viewport. There are several issues that I cant get into more detail because I tested it over a remote desktop connection and it was fairly laggy but I compared in that same session also the ragdols from my original project and even through the remote desktop the results were worlds apart. When im back home and have access to a proper machine for testing Ill get you some more info. But right now things have drastically changed for the worse in terms of certain ragdoll behaviors. Hopefully it gets solved even before I get back to testing it better in the next year.
