Playback after Rendering is Slow

I’ve rendered in the viewport frames 1-2000, but when I play them back, they play back like it’s slow motion. To be clear, it’s not the animation playback within blender, it’s the viewport rendered animation playback (which should play back at normal speed). I feel like there’s a setting button or something I need to change, but I don’t know what that might be.

If someone can help, that’d be great!

Realized my fps was set to a lot lower than my file required!
