well… I tried, it happened to me to be the default 3d render after an update.
If you have already made a similar project and you are experiencing now low performances after the update you can always try to downgrade to the previews version.
I am on the latest version of AE, but I am on windows and I have not experienced differences in performances with the 3d layers.
Your settings of AE seem correct… I don’t see why it should perform right.
You can check in video rendering and effects in project settings if switching between Open CL or METAL can help.
…and use 8bit per channel you you don’t need 16or32…
I hope it helps.
