1.20.1 Annoying Lag Spikes when playing after a few minutes

[Cripjey]

hi, i always had this issue in my pc whenever i play minecraft with mods, no matter if i only add 1 or 2 mods, i always have these annoying lag spikes everytime i play, my pc's cpu might not be the best, but i have some friends with worse pc's than mine and modded minecraft works perfectly fine in them.
Maybe is some configuration error within my pc or game, whatever the case is, i have this spark profile i created earlier so i can get some help from you guys

You allocated too much RAM to the game, so the OS, drivers and other things are fighting for resources.

Close as many things as you can when playing, allocate 3GB or 3.5GB max, do not set a min. In task manager go to the startup tab and disable things you don’t need to start and have always running when you turn on your PC, but ignore the AMD ones in the list (they’re needed).

Use Java 21 instead of Java 17. Consider removing Alex’s Mobs. Update your Radeon drivers (see the FAQ).

Consider buying more physical RAM for your PC
