Game has way lower performance than versions before

I quited playing minecraft for few weeks I think, it was 1.17.41 and now I started 1.18.1 and I have way less fps, can't make it stable 60fps at any point. Cheers do whatever you want with this information, I can assure you from checking task manager that there is no any process slowing my PC down, it's just Minecraft taking any great resources
