OCIO Color Management slow

When I change my OCIO Configuration to ACES 1.2, my after effect timeline can no longer playback in realtime. It will cache, and everything looks normal, buy playback is approx 1/2 to 1.3rd of the speed.
When I turned it back to Adobe Color Managed, it plays fine. (But looks incorrect)

Has anyone experienced this?

1. OCIO in general is more computationally heavy on the system than the icc profile based Adobe Managed.

2. I would recommend using ACES 1.3 as the transforms there are mathematically defined rather than LUT based so don't suffer from lack of precision. The OCIOv2 configs may also be a little bit faster.

I get this error with 1.3

any idea?

On existing effects or a newly added one? Because the 1.3 config uses different names for the color spaces than 1.2 existing OCIO effects in the project may need to be refreshed by clicking reset.

I should note that this is on Windows 11, and the issue persists across AE 2023, and 2024.3
