[iruma77]

So I just started TTW on mo2 game is running smooth but I am having issues with frontier when im a child in the fo3 areas like vault 111 and vault 112 issues like stuttering to run down or up stairs and when I fall its very slow I got the hot fix for the frontier does anyone know of a patch or a fix to this the game is still playable with no crashing just the physics issues.
