Minecraft lies despite OptiFine?

Dear community,

My MC is new at Hypixel. I'm at 10 fps. I used to have 70, what should I do? Optifine settings don't help. That with dr priority on high also brings nothing and also on 2g more I may not have I only have 4 g…

How high is the render distance set?

5 chunks. Further urnter not otherwise it is practically unplayable

HM ok. What is set under "Performance"?
Do you have a texturepack in it?

No. I had never changed the settings and it was still better earlier

Have brought nothing so far
