As a youtuber, video quality means a lot to me and getting good FPS in minecraft can be difficult if you don't know what you are doing. So I bring to you the Ultimiate FPS guide for minercraft. I have installed many unstable mods and added shaders for the difficult task of keeping them installed but improving the FPS. We take the game from an unplayable 2 fps all the way up to over 130+ fps!

This tutorial assumes that you already know how to add more ram to minecraft but if you on't read below

How to add more RAM to minecraft:

if playing on the standard launcher go to edit profile and down to java settings (advanced) then tick the JVM arguments box and paste in the following
Code:
-Xmx8G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn1G
Change the 8G at the begining to the amount of ram you want to use for example if i wanted to use 3 gb of ram i would change it to 3G.

if using the technic/ftb or the AT launcher there is a settings button somewhere on the launcher that alows you to selct the amount of ram you wish to use.

Remember not to use all of your ram as the computer needs it for other things as well!

Be careful with java arguments. Ones that work for Java 7 do not work for Java 8. The java version you have matters alot. The old Java 7 arguments actually make Java 8 give you worse FPS.

I'm gonna give it a try, my GT540M is not that powerful.
Hope it helps as much as it does for me :)

That's good to know, i'll have to test on 7 and 8 and see what effects are different and update the post, thanks for the heads up

Also do not give minecraft more than 4ish gigs of ram, java gets lazy after that and doesn't end non-needed processes as quickly, leading to lag spikes when it finally acts. Thanks for leaving this here though, may link it in the future
