2 bugs in me1 in mass effect legendary edition

This first one is game breaking. In virmire if you kill the indoctrinated salarians in the cage it drops the game fps to 4-5 from a stable 60 fps.

The second bug is not gamebreaking but annoying. Sometimes if you are on foot your character gets stuck aiming in one direction no matter where you turn your camera the character wont turn and when trying to walk it dosent follow the camera rotation but the body so sometimes to go forward you have to press a instead of w and stuff like that, if you are in the mako when this bug happens the mako just stops and you cant move it, the animation of the wheels plays but the mako dosent move, even if you use thrusters or boosters. If you get out of the mako in this state it teleports to a location where you would have drove to while pressing buttons in the buged state, and the moment you get out of the mako the character gets stuck aiming in one direction.
