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. Step Run Minecraft.
2. Step Open the Task Manager (CTRL + ALT + DEL)
3. Step Right-click on Minecraft and select Go to Process:
Minecraft Windows Process
4. Step 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. Step 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

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. Step Open Minecraft and log in
2. Step Click on Options and set Limit Framerate to ON and Graphis to FAST
3. Step 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.

    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.

    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?

    @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)

    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.

    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.

    Right. All you guys out there using laptops, make sure it has sufficient cooling space. Don’t put your fan on a table or on the floor, it’ll just burn out your laptop and make it less efficient, hotter, therefore making Minecraft lag. Make sure your fan isn’t dusty, so get the hoover out and clean it up. For desktop computers, I would say the best thing you can do to make your Minecraft run fine is by defragmenting your hard drive. Minecraft relies heavily on your hard drive – it saves your current game every 2 seconds for god sake. So it is vitally important not to have your hard drive cluttered with random crap. Clean it up, defrag it, and you should not only see Minecraft improve performance, but your computer in general.

    This is the computer that I run Minecraft on. It runs fine:
    Intel Core 2 Duo E7600 @ 3.06Ghz
    4GB DDR2 333mhz RAM
    Nvidia GT218 512mb graphics
    500GB 7200RPM hard drive.

    This is a pretty run-of-the-mill average desktop computer. Minecraft runs from 50 to 100 FPS. That is all.
