»Used to get high fps, but now very low

Hey guys,
I have been playing on anni yesterday and I had around 100+ fps. Now I am getting less than 30. I even installed optifine and it didn't do any difference
Can someone tell me what's the problem?

Processor: intel i5 2.40 GHz
RAM: 8 GB
Graphics card: 2 gb radeon graphics

That's all I know. If u need more info, tell me

 

try changing ur render distance

 

Nope, render distanced decreased to 4, didn't work

 

Go to your toolbar right click it and select start task manager go to processes find javaw right click it and set priority to high
this might work
also install optifine

 

couldn't find javaw
plus I already have optifine

 

You could allocate more ram into MC. Just search for it. It might be low fps, because Minecraft doesn't receive enough ram. Or there's a bottleneck in one of your components.

 

Disk defrag , CCleaner , delete stuff that you don't need anymore

 

Crashed:

minecraft needs to be opened srry forgot to mention that

 

Don't use your whole memory. 4-5 GB are enough.

 

can u tell me how to set priority to high? lol

I only used 2...
I don't how to do it I edited profile, enabled JVM, changed 1G to 2G

 

There's your reason, amd gpu...

Kidding, minecraft doesn't even use your graphics card.. But seriously don't buy anything from amd related to graphics.

 

I agree, well AMD is the low-budget company :/

 

select javaw
right click the javaw
drag ur mouse over to set priority then click high
then change priority
u also need to do this everytime u join mc

 

another simple solution is to get a new pc xD, Joking try and make sure what ever you have open on your PC at the same time is not CPU intensive like some apps are

Guys none of this works.
I just cant believe it, I cant play because of low fps
How tf did my pc drop from 100 fps to 13...

It is just freaking annoying...
well I think no more minecraft

 

is there a program or file you downloaded that maybe is a virus? virusses can effect your speed a lot.

 

just download optifine trust me Will make FPS 200+
