Describe the bug
When using kleider's custom renderer alongside EMF, fps drops can be noticed the second you try to look at another player or yourself using F5. if only thoses mods (and cloth config & ETF) are installed alongside any mod that uses kleider's custom renderer features, it might not be that much noticeable if you have a good setup (in my case, I only go from 300 fps to 40). However, on a larger modpack, I can quickly get from 400 to 15 fps, which can get pretty annoying for a server with multiple people. The thing that I noticed is the fact that the FPS drops usually stops after 10 seconds or so.

To Reproduce
Steps to reproduce the behavior:

1. Create a world with EMF, kleider's and any mod that uses kleider's renderer
2. Press F5 to see yourself in third-person
3. Check your FPS

Screenshots

Here is the spark profiler of my large modpack, "hexagonia_two" is the mod that uses kleider's renderer

(please complete the following information):

• Minecraft Version: 1.20.1
• EMF version :2.4.1
• Does the issue persist with only EMF installed?: No, as its a compatibility error
• if applicable, provide your modlist or log:

Additional Informations
if you want to try the issue for yourself, just so you know "hexagonia_two" is not public, so you might need another mod that uses kleider's custom renderer API for that
