Maya :: Time Slider Running Super Slow When Scrub Through Animation

For some reason when I scrub through my animation, it runs really slow. And it has nothing to do with my computer itself. It is the particular file. I tested this by opening up one of my others (i saved in iterations) and they all scrub just fine. All I was doing was animating with a rig, so there isnt any extra polygons or whatever. And on top of that, it worked just fine before I exited the program earlier, I even playblasted it and everything, and then I looked at the playblast later and decided I wanted to change something, reopened the file, and the timeline has been chugging ever since. I tried opening and closing maya already.
