Fusion won't cache anymore

Since I got to the 20 beta (I'm on the most recent update)
Fusion doesn't cache anymore, the green bar in fusion will load for a frame or so and change, it used to be I could play a clip and it would cache so I could get better playback
Now that doesn't happen, I have checked all my settings it should be working
Anyone know how to fix it? I've seen a few other posts mention it as well
