Help me!!!!! I, on 1.4.7, used to get about 107FPS when playing but now with 1.5.1, I lag SO much. I droapped to like 15FPS! Sometimes it says 30FPS but its actually like 10FPS
Here are the methods I tried (none worked):
Optifine
MCPatcher
Set Priority (In task manager)
Razer Game Booster
RAM upgrade (Java settings)
RAM upgrade (Shortcut ram)
I even go on Tiny render distance and I still lag! I used to be able to use the Optifine setting Extreme and I would get like 90FPS (On 1.4.7)
Please help me it is terrible!

clear minecraft jar or unpatch with MC patcher

I have the same exact problem, just I drop down to 1FPS (my computer's old and was dropped 10 times, like literally).

I need MCPatcher for my 32x32-64x64 texturepacks.

Are you sure 1.5.1 doesn't fix it? It totally boosted my FPS back up.

What kind of computer do you have?

Go to task manager (with Minecraft open as well.) Check your CPU. Any processes that are taking up a lot of space?

Hey Um, Its fixed. Just if u wanna know, my specs are:
RAM: 6GB
Processor: i5
Hard Drive: 500GB
OS: Windows 8
I bought it last summer.
