AE super slow in M1 Max Macbook Pro 2022 - What am I doing wrong?

i have the same problem and can not preview more than 2 frame. so sad........ really regard to update the sysyem and AE 2022

I'm also on an M1 Macbook Pro, and it's great. What version of AE are you using? What is in the comp? What are the frame size and frame rate? What are your Preferences and Project settings? 

I have Mercury GPU turned on in the Project settings (Shift + Option + Command + k).

I have Preferences/Media and Disk Cache (Option + Command + 😉 set to only 40GB, so it will clear faster, and my internal storage is about 75% full, Preferences/Video Preview set to Enable Mercury Transmit, Preferences/Memory & Performance set to 4 GB for other apps because the OS hates memory allocations that are not even multiples of 4 GB, Enable Multi Frame Rendering is on, and I have 10% of the CPU allocated for other applications. 

My comp panel is almost always set to Auto, I work mostly with 4K footage from professional gear, and I avoid, reinterpret or transcode footage that is highly compressed or variable frame rate (from a phone). I have the entire Boris FX suite, the entire Reg Giant (Maxon) suite, all of the Video Copilot effects, and about 60 scripts and extensions. Everything I have has been updated to M1 compatibility except AE Flame from AEScsripts.com and Knoll Light Factory. I hardly ever use either of them, but if I need them, I can open AE using Rosetta.

Check those settings, and make sure that your boot drive has plenty of room. Don't run any unnecessary apps while you are working in AE, (Web Browsers can be a tremendous resource hog on some websites). Check your Activity Monitor for bottlenecks. If you use external drives for media, make sure they are solid state and Thunderbolt 3 or 4 compatible. Make sure you don't use cheap cables for your external drives. A USB-C cable has about 1/10 the bandwidth of a good Thunderbolt 4 cable.

Let us know what you figure out.
