Bug: Ram Preview not real time
Here are my computer spces:
MB: Asus X299 Prime Deluxe
CPU: i7-7820X 3.6GHz
RAM: 128GB DDR4 (16GB x8)
GPU: Asus strix 1080ti OC x2
Harddisk: SSD 960 EVO M.2 1TB
Since the last year version, I've just noticed that the Ram preview is not in realtime, even though the green bar already filled up. Now i am working on version 17.0.4, the problem still here.
No matter how simple of my composition, it just happened when the "Project Window" contain many stuffs. Especially there are many footage imported inside the project, even though I didn't use them all.
By the way, it just only happened on PC, it worked fine on my Macbook pro. The only way is just reduce the project, but sometimes this is really annoying when I am working on the commercial project.
I recently made a tutorial for Hong Konger, please check out
9:01 - 9:11 & 14:30 - 14:46 , I put the info panel on top right corner for showing the playback speed.
Just accidentally recorded the problem, but yeah..this is what i am talking about.

Hello! I can see what you describe in the linked video; thank you for the example. There are a few options in AE that will take an un-optimized path and potentially slow down playback. Please check your "Display" preferences to see if "Hardware Accelerate Comp, Layer, and Footage Panels" is toggled on, and also check your Preview panel options to see if you have enabled "Show overlays and layer controls." HW accelerate defaults ON and overlays default OFF, which are the settings that should allow for optimized playback. At your comp size, I would expect cached frames to be able to hit real time 25 fps.
