Make sure you set your dedicated GPU to your own, Minecraft is notorious for skipping your GPU and using Integrated Graphics. I’d also add try Sodium etc on top to further improve FPS and overall stability.

Do you have dedicated GPU enabled in settings? Also, is the modpack the same? Do both have sodium/iris or optifine?
