I dont get more than 1 FPS both in game and at the options while in game. Only runs smooth on the title screen.

I have allocated 7,5 GB of memory, no driver outdated, the mods said are removed, I also added OptiFine and lowered most of the things too. Tried with a 250+ mod modpack, also didnt lowered everything, 25-30 FPS. Only does this in this modpack. Using the original launcher (twitch launcher isnt working for now, i think its because CurseForge is beta in Overwolf). Didnt added any mods or JVW arguements. This modpack is running perfect on my other computer, doesnt work on this tho for some reason.
