Whenever i use forge i have performance drops but when i use vanilla it works totally fine.
I'm using both forge 1.12.2(14.23.5.1854) and forge 1.16.2(33.0.61).
My pc specs are
AMD Ryzen 7 2700x
16GB RAM
RTX 2080 TI 11G
Yes, my drivers are updated, i've allocated about 7Gb to Minecraft and i'm not bottlenecking.
Also when i use 1.12.2 some textures from the thermal series mods are corrupted.
Before this problem i was running about 100 mods in 1.12.2 with 100 fps, now it's running 10/5, and the textures weren't corrupted
