I'm having issues with the blockbuster mod, when I start a scene with the playback button major lag begins and my fps drops down to 4 or 15. I've tried everything down to changing my ram to downloading better performance mods and nothing seems to work, I want to mention i'm also using optifine shaders. If anyone has or is experiencing the same issue and found a way to reduce or fix the issue let me know, I would like for my scenes to be much smoother. I allocate 8GB of ram into the launcher just for anyone wondering.

PC SPECS:

AMD Ryzen 3700X 8-Core Processor
Radeon RX 580 Series
CPU - 16 RAM
AMD Radeon Graphics Processor (0x67DF)
CYBERPOWER PC TOWER
64-bit operating system, x64-based processor

This issue isn't because of Blockbuster mod, it's because of Emoticons mod. Either stop using Emoticons morphs or change to _simple variants.
