Modded MC extremely slow after MC Re-install

[Ghostbuster3210]

Heyo, I recently had a new computer built, because my old one was a pile of steaming garbage.

One of the things i had the PC guy put onto the new computer was my .Minecraft folder
i play with about 24 mods, including optifine, Starting it up, for the first time on the new computer, it played perfectly,  about 327fps average with fancy graphical settings, and about 117 with shaders. Then during the night, i began to have issues with my world crashing, which in my sleep-deprived stupidity, lead me to delete and completely re-install minecraft. After that re-install, nothing has been the same. Using the exact same mods will now get me about 23-30FPS and no matter what i do will change it. I've tried installing the mods one by one, and its not caused by any specific mod. No matter what order i install them in, having all 24 will drop my frames and make the gameplay unpleasant. I have the latest version of forge running, which is the same forge i had before i re-installed everything.

My specs are:
16Gb DDr4 ram
Rx580 8G
AMD Ryzen 5 2600

If anyone has any clue as to what's causing this, please consider telling me.
Edit:
