hi i have founded a persistant bug in a lot of missions. 

on certains mission my inquisitor lost his legs, suddenly the legs dissapear or glithched funny over my character heads... the problems is when this  happens, the game optimization turned crazy, very slow and with a lot of frames jumps, this is very annoyed for play with him, even provoke my inquisitor death

(i put more down profile on graphics options: 20fps, low textures, no phisics, no shadows...etc) but the problem persist... the weird of this is that only happens on certains missions, in others missions with high graphic options even atmospheric effect, the game works fine and fluid

Are i doing something wrong?? because no legs meanig death on slow motions XD is a madness

thanks for your time
