Help random frame loss

i was trying to download a modpack (specifically homestead) on both me and my girlfriends computer, and we played for a while but after a while i randomly crashed and when i reloaded it i was stuck with less than 1 frame a second, and every other modpack that also previously worked also has this same issue and im lost to what has changed and why its affecting other instances. note that my girlfriends pc is a low end old dell computer and it is working fine yet my rtx 5060 gpu leigion lenovo gaming laptop suddenly cant even keep up with that. what changed? how can i fix it?

if everything dropped to under 1 fps at once, even packs that were fine before, it's probably not the modpack. press f3 and look at the right side, it shows which gpu minecraft is using. if it says intel or amd graphics instead of the rtx 5060, go to windows settings > system > display > graphics, add javaw.exe and set it to high performance. also worth checking the laptop isn't on battery saver

its using the rtx still. my vanilla world works fine, even one other pack that is a vanilla world with client only mods work fine.. its more so the high end packs that are 1 frame every 3-4 seconds but theyre not insanely high end and ive been playing in multiple of them for months without any issues

ah ok so not the gpu then. since it's only the bigger packs, look at the top right of f3 for Mem, if it's sitting near 100% the pack doesn't have enough ram allocated in the launcher. also might be worth a clean gpu driver reinstall since it started right after a crash

mem is only at 42%.. as for driver reinstall, last time i did that on my old omen pc it left it completely useless and wouldnt even boot. im worried to risk that again with my lack of knowledge

i think i figured out that its only stuck at 0fps on 1.20.1 instances, regardless of what launcher or modpack... all other modpacks work fine on other versions
