Note:This is my first guide on this forum so sorry if I said anything wrong.This will only from computers capable of alteast opening the game and play or just open the game to being able to play it smoothly . WARNING:If anything breaks,or goes wrong,i am not responsible since you were the one who did it Welcome to this guide everybody,today I am going to show how to increase FPS in Minecraft,this is a easy step by step guide,and does not need a lot of work to be done,and in some cases,it doubles the FPS Note:This guide will work on either premium or cracked Minecraft and will work Windows,MacOS ,Linux.It is easiest on Windows,but on Linux,it gets the most FPS.This guide will work from Minecraft 1.7.2 and above,if you play a older version of Minecraft,then you can still increase FPS,but not as much as 1.7.2 and above.This will work on both old and new computers but has most effect in the game on older systems,new systems may also have effect but it might not be huge or might not be noticable Step 1: Reinstall Minecraft: by going to Run by pressing Start+D and type %appdata% and deleting the .minecraft folder or renaming it to something else and download the game again [if want to revert later ,rename it to something else,rather deleting it,so the game has to download .minecraft AGAIN and be faster),this is one of the most effective ways of increasing FPS,since when it is full of unnecessary files it has to load like game saves,log files,etc.This step can be skipped,or you can delete unnecessary files in the .minecraft folder without having to lose ANYTHING WARNING:This will delete everything if you decide to delete the .minecraft folder or rename it (renaming it wont lose data but you wont be able to see the game files unless you rename the original game folder back to .minecraft,if not the singleplayer game saves,any modifications and the server ip's and the entire game stuff is gone,so back the game up if anything does wrong,since you will have to download the 145 MB of the entire game,so do it if you want to. Step 2:Update Java:This is not that effective but still increases FPS by a small margin,go to https://www.java.com/en/download/manual.jsp and download the latest version for your os [If your OS is 64-Bit then download 64 bit] go 64 bit [If you have a 64-bit os] and 32-bit (If you have a 32-bit os or 64 bit os and a 32-bit browser) so the game can take advantage of 64-Bit Java [Do not use the in-built Java from the Minecraft launcher since that is a old version and change the java to the latest one. You cannot install 64-bit Java on a 32-Bit OS but you can install 32-bit Java on a 64-bit os Step 3:Update your Graphics Drivers:Even though Minecraft is CPU intensive,you cant play it with a i7 and a Voodo (means you cannot play it with a very new CPU and GPU)but sometimes,graphics driver updates can really increase the FPS in the game,so download a free utility called GPU-Z and see what Graphics Card you have and go to their website (eg:www.amd.com) Note for nVidia and intel users that the driver download page is www.geforce.com and for intel,it is downloadcenter.intel.com.Download the latest drivers for your Graphics/Video card and play Minecraft,it should give more FPS. Step 4:Install Optifine:Optifine is a Mod that adds some more video settings the game,this is one of the most effective things to do, go to optifine.net/downloads and download the latest version for your Minecraft version and you need to run the original game version alteast once.When download is done run the file [For Linux or possibly Mac users,go to Terminal and type cd [which directory or path the file was saved to] and type java -jar [file name] ].When it is done,it should create a profile in your Minecraft Launcher called "Optifine" and click "Play",then it should start the game with the Mod and go to "Options" then "Video Settings" and you should see a LOT new ones,for oldcomputers,go to each sub menu and set them to "Off" and "Fast" (depending on what option it gives you).This part is done,on new computers which can aleast run vanilla minecraft (normal Minecraft) at 30 FPS,you can choose what to choose.Changing the settings might effect in looks,but the human eye cant see a huge difference.Go to Performace and change the chunk updates to 3 (which balances the fps and world loading speed) and enable Smooth World and Smooth FPS. Step 5:Allocate More RAM:Minecraft by default sets the ram to be allocated by the game is 1 GB,if your computer has more ram than 1 GB (eg:4 GB or 2 GB) allocate it some more but do not allocate full ram.Go to your launcher,go to Edit Profile (choose Optifine) and in newer Launcher (premium launcher) go to Launcher options and go to JVM arguments and click the checkbox and check it and clear the box and type -Xmx2G (G is gigabyte and MB is Megabye in this) and replace the 1G in -Xmx1G with a higher number so it has more ram allocated and Click "Save" and start the game TIP:Run Minecraft in a Window for MUCH Better FPS and do not run anything else while running Minecraft (eg:Google Chrome) since it will impact the CPU and RAM more since it has to multitask (Do this on older systems,sine that is really where it helps) Done ! Now You can enjoy playing Minecraft with better FPS Hope you enjoy playing Minecraft/continue to enjoy playing Minecraft And at last Have a nice day
