Completely Unplayable

SPECS: Intel Core Ultra 7 155h, NVidia RTX 4070 Laptop, 32GB DDR5 SODIMM RAM (12gb allocated)

I don't know when it happened but recent updates have rendered this pack entirely unplayable. V1.5.9-V1.6 all ran perfectly fine and sometime after that, something must have happened to completely kill performance. When I played extensively before, it ran well for what it was. I had to crank down my settings a bit, but I still ran it at a stable 100+ FPS under normal circumstances and 60+ FPS when near a lot of stuff. Nowadays a fresh, empty world is running at anywhere from 5-70FPS with constant drops down to 0. It is genuinely shocking how bad performance has gotten, and although this modpack has always been behind it's competitors in terms of optimization, it was never outright unplayable. Now, it's completely impossible to do anything thanks to the constant lag. (and yes, I've checked my NVidia settings).

I wouldn't install this until the performance issues are fixed.
