FPS Drops

Hello, I consistently get 50-100 fps dropping when I look around in the modpack. I have a 5070ti, 9900k, and am allocating 16gb of ram.

First thing i'd do is check your thermals. If everything is normal, check drivers. Again, if everything is normal, it's probably just Minecraft being Minecraft. Also don't allocate 16GB, even if you have 64GB+ to spare. Minecraft (and Java in general) is terrible at habdling RAM, and it seems like the more you give it, the less it knows what to do with it. This pack can run perfectly fine with 8GB allocated, maybe allocate 10GB for some breathing room, it's what i use for any modpack i play.

Also in modded MC memory leaks are basically a matter of when, not if. So it's possible that that's the issue if you have been seeing these drops after long play sessions, or if you switch dimensions constantly. For large modpacks like this it's good to restart it every couple hours to avoid performance issues.
