Misc - Fusion Disk Cache.

If you turn "Fusion Memory Cache" on. The rendering priority will be: To RAM then To storage.
Drop may happens when the software switches between the image stored in RAM and in storage.
When it reaches Fusion Memory Limit, it will push images from RAM to storage, causes refresh rendering and drop fps too.
Low latency storage is required.
Format:
.Raw, doesn't need to pre-render, large file size.
Compressed like JPEG, PNG, need pre-render (slow), small file size.
Lock & Unlock: Update or Not update.
Missing images or update images needs a refresh, then cause drop fps.
*PS:
If you ask how to reduce lag when using Optical Flow, then there are two ways: lower resolution (whatever the way you lower resolution) + lower Optical Flow settings. The video here is not about that issue. It's about how to reduce lag in Fusion or smooth playback by using Fusion Disk Cache.
