ME3 Tuchanka Cutscenes Lagging

I just played through this mission earlier and the cutscenes messed up starting from when you call Kalros to attack the reaper until the end of the mission. The cutscenes were very slow and jittery and the audio was way off. Part way through the cutscenes it would just cut to the end of it and the audio would continue on. Because of this I missed the scene of Kalros attacking, attacking again, and taking down the reaper. It also messed up the cure dispersal scene.
