Stuttering, Small freezes and framerate Issues

[Damascus Rose]

I think this is a way to reduce the framerate glitches:
First off, defragment your hard drive. this one helps with the glitches as a sound is about to play.
Lower your settings, especially SSAO.
I also made my game a lower resolution than my screen because the frames always seem to be a bit buggy at native resolution.
I updated my graphics drivers too.
