How to make Minecraft run faster (less laggy)
Is your Minecraft lagging a lot? If so, you might want to make Minecraft run a bit faster. This tutorial is intended for Windows-users only.
Tip: Before reading this tutorial how to make Minecraft run faster, you might want to read this extensive guide how to make Windows 7 run faster, as this will most likely help you to make Minecraft run faster as well!
1. Change Minecraft Server
If you are logging into a server to play Minecraft, consider changing the server. If the server is located somewhere far away from you it might slow down your Minecraft.
2. Download Minecraft Offline Client
If you are playing Minecraft online (for free) you might want to consider buying the game and playing it via the offline client. This might have a positive effect, since a slow connections might make Minecraft run a lot slower than it could and might possibly be even a cause for major lag spikes.
3. Make Java Run Faster: Make Minecraft Fly
Minecraft is a Java game. One thing I hate about Java is that it consumes a lot of CPU and is often responsible for slow websites, websites crashes and what not. As you can imagine, giving Java more power (via CPU priority
1. Run Minecraft.
2. Open the Task Manager (CTRL + ALT + DEL)
3. Right-click on Minecraft and select Go to Process:
4. Right-click on javaw.exe and hover over Priority. Select High Priority (Do not use realtime if you don’t want to crash your PC)
5. Make sure Java is using all of your processors or Minecraft will not run as fast it could. To do that right-click on javaw.exe and hover over Affinity. Select all CPU’S:
4. Minecraft Graphics, Framerate, Memory Usage
Show FPS in Minecraft:
Do you want to see how much memory Minecraft is using and display your FPS? Press F3!
As you can see Java is a memory-hog and Minecraft needs some resources to create those really huge worlds. On my system only 45 FPS and 1GB RAM dedicated
Tip: Minecraft (Java) requires a lot of RAM, consider upgrading your RAM to make Minecraft run faster. 512MB RAM are WAY to less for modern PC’s and applications. You should at least have 2GB RAM (Windows 7 32-bit), but 4GB (Windows 7 64-bit) or more is recommended.
You can limit the framerate of Minecraft, which might help to to make Minecraft run faster on some systems. Also, make sure that your graphics are NOT set to “fancy”. Additionally, you can set the render distance to SHORT (can greatly reduce lag and improve speed)
1. Open Minecraft and log in
2. Click on Options and set Limit Framerate to ON and Graphis to FAST
3. Set Render distance to SHORT

Only #3 is a viable speedup for general usage, and it’s not a good idea in general…and quite ugly on the system level (you should see the code that handles that part of Windows!).
Actually, Minecraft has been found to run faster if it’s only allowed to use the first core of the first processor. Java works improperly on more than that.
let me say this because it is true windows 7 and vista suck im stciking with windows xp till the day microsoft stops supporting it.
@Muhammad
They already have stopped supporting xp, to a degree(Too lazy to find the article, just google it) but I agree with you. Vista was an abortion the day it came out and 7 is just xp with glitter. Heavy, slow, useless glitter.
Can u help me. Im using a cannon and each time a i fire it, it will destroy the blocks around it for a second then they come back, Then after that the tnt to fire it become big and white and wont go away (no mass just the shape their) i thought i was this but its not help please
My computer gives me the “Access denied” error when I try set java’s priority higher.. and I have it set to “run as administrater”
So I have done all those things, but I think it is different for me. I use a Aspire One Windows 7 Starter Laptop, it is a notebook, and I think it is just the computer but one day I was playing Minecraft and it was like the best graphics, no lags, nothing wrong, it worked so good. Now all it does is move the screen every minute and I can’t play at all… I don’t know what I did to make it happen but does someone know anything?

Can someone help me with my fps issues. Here are my specs.
Manufacturer: Acer
Model: Aspire Z5600
Processor: Pentium(R) Dual-Core CPU E5500 @ 2.80GHZ 2.79GHz
Installed Memory(RAM): 6.00 GB
System Type: 64-bit OS
Any help would be greatly appreciated:)
THIS DOES NOT WORK it will only fuck up your computer, i tried the priority thing and now my Hammer world editor lags, minecraft is like a picturebook and im not even going to attempt portal 2. just leave minecraft alone and get rid of the lagging world because thats not gonna fix it, especialy if it a millienaire world, get off your lazy ass and cut more wood instead :) yes i know why you got the mod and yes someone invented an auto tree farm. have fun on your fast minecrafts and computer cause i sure wont be able to, dont take it for granted trust me on this
I just bought a very good laptop With an incredible graphics card and it was about €1400 but my minecraft is running very slowly i get like 23 fps on short. I am very sad about this and i think it is a software problem because all my other games like black ops are running just without any lag at all. I tried everything to fix minecraft but nothing worked. Can someone please help!!!
Heeey, i newly bought a pc for like 1000€ and it got 6 RAM on it, but not the best graphic, but minecraft is lagging all the time, it is loading around 23 fps, wich makes it really laggy, so please help me, i have no idea what to do, I tried to take max fps on options, but it was still incredible laggy, if u now of anything that could help, then i would be gladly to “hear”
@Carl,
You should tell us how much memory your gpu has. Minecraft uses OpenGL for ALL rendering which uses a lot of the gpu, and if it is not powerful enough, you will definitely have bad fps. (bad enough mc is using java, it is extremely inefficient.)
it’s kinda funny I think. I played BF3 and Skyrim with 60 fps around
but when it came to minecraft, it dropped to 30 fps or stutter and freezes for some seconds every 30 seconds
plus, the 1.8.1 has a problem with fps drop. something in the script, i think
even worse, if your world is bigger than 100mb.
plus it’s java based, plus it’s uses OpenGL
they need another platform. not flash, definitely. maybe using game engine (but not gamebryo lol)
@Jeems
Try your Processor if it is 1.5 GHZ or lower then it wont support your minecraft and if your processor is good then try Getting a Nvidia Geforce Graphics Card with at least 1GB i had this problem then i got a Nvidia Geforce and I can Run Minecraft With Far Render Distance Fancy and Smooth Lighting, Bobbing on….. Meh last tip is getting the Optifine Mod it lets you edit Minecraft properties in the Video settings……….. i hope this helps
Minecraft is extreely reliant on your CPU and RAM… barely reliant on your GPU. 16 bit graphics. Intel HD can handle it. So can almost any semi-modern nVIDIA or ATi card. Here’s my current system: AMD Phenom II Quad-Core black Ediion 3.2GHz, 4GB 1600MHz RAM, 1TB 7.2k SATA-III HDD, ATi radeon HD 6850 1.0GB GFX, Windows 7 64-Bit – I run Minecraft at 150FPS with a 64×64 texture pack and 1GB RAM dedicated to Minecraft through mcpatcher.

16GB DDR3 RAM

Come on wtf, there is definitely something wrong with Java because I’m getting lag spikes every 5 seconds… this NEEDS to be solved.
Some of the replys on here are so idiotic, changing process prioritys will NOT ruin you pc. But I do agree with who ever said minecraft works better using just one core. The sad fact is, Java sucks. Its WAY too processor heavy for what it does. I’ve changed my priority on java to highest and it really improved my lag spikes. But if you have a rubbish pc theres nothing you can do to get minecraft working properly and look good at the same time. It may look simple on the surface but it’s pretty complex under the hood.
Can someone please tell me how to “just use one processor”…? where do I change settings?
i put the setting thing on and minecraft runs perfectly on far render distance :)
