API Enhancer doesn't seem to work right on 1.12.2 - massive performance impact

[UnixRonin]

Looks like the API Enhancer's going to need additional work to make it usable on 1.12.2. I tried loading it and never even got to try any fancy SM moves with it, because my frame rate immediately dropped to 2fps.

Low priority issue at the moment, compared to getting the main part of the mod working properly, but just getting it out there on the record.

Is this only with Smart Moving? Or other mods too? What versions?

[UnixRonin]

This is with a fairly sizeable modpack, but the only change was adding the API Enhancer. Smart Moving without the API Enhancer has no discernable performance impact.

I can throw up a minimal test server tomorrow and retest with just vanilla plus Smart Moving plus the API enhancer and see if the same thing happens.

Client of course also has RenderPlayer, RenderPlayerAPI, and ... one or two other client-side only things I can't remember off the top of my head without comparing side by side. WAILA/HWYLA bits I think.
