Bioshock Infinite is an amazing game first of all, but I am having an issue with the stuttering. I was running the game on ultra and noticed that I was experiencing what I thought was a frame rate issue. However, I was still getting stutter on lower settings. I was puzzled, so I downloaded Fraps to check my FPS. I ran a mission and unlocked the frame rate/turned v sync off in game. I was averaging a surprising 100-125 FPS, but was still experiencing choppiness. I turned v sync on in game and it seemed to smooth out, but my fps was capped to 60 and during moments of intense action it would drop closer to 30 and run terrible. Why, when I unlock my frame rate, does my fps run at a "respectable" 60+ but the image feels choppy and un smooth? Is it screen tearing? I am confused.
