Minecraft massive frame rate drop?

Minecraft massive frame rate drop?

Added (1). Ever since the most recent update I can't play minecraft without jarring and almost nothing framerate I've tried multiple fixes and optifine and all that and nothing changes. I'll stand still and have like 90 frames and start moving and have 15-9 frames AT THE LOWEST SETTINGS.
I used to play at max optifine settings with a stable 40-50 frames but now… I dunno.

My Specs

2.0ghz quad core (Some AMD APU processor)
6gb Ram
Nvidia Geforce GT 630 (PNY 2GB Edition)

Change the setting
