I just need help on why i used to get 40-50 Fps and now all of a sudden im getting 1-6 even with optifine, i also trun of unessesary programs running in the background but nothing helps. Any ideas?

no idea.. must be the mods you installed.. go vanilla and redo 1 mod at a time until you find the bad one.

Well im on a tablet right know because the computer over heated so it might be that theres something wrong in the computer because this is the first time it over heated :/
Plus some other programs where slower, so it might be a combination of a mods and something going bad in my hardware thats causing the problem

Edit
My computer is running again, when i looked in it the heat protector looked like it was about to come off, so i  fixed it i hope. anyway i'll see what mod is being stupid
