Let's get started on reducing your lag in Minecraft!

If you don't have time to read the entire blog, skip to the end where I give the bottom lines of each tip.

You will learn:

  • Tons of helpful tips and tricks
  • TNT and redstone advice
  • Controlling your computero s performance and speed
  • Getting optimal performance without buying an expensive gaming computer (Alienware etc.)
  • Very helpful tips from fellow players

Io m assuming:

-You know your way around playing Minecraft and opening menus.

-You know how to open Control Panel and/or perform basic maintenance.

-You may know how to install mods.

Section 1 o Basic Settings

First off, these are some basic settings to reduce a decent portion of lag in Minecraft. The first thing you do when you just have a clean copy of Minecraft (no mods or shaders) is to go into your options. Press the Esc key on your keyboard (top left-hand corner) and it will open up the menu when you are ingame. In the main start screen, you should see a box labeled "Options". Click on options and choose video settings. You should see this in your screen (see image below):


Now change the graphics settings! (Click each of the boxes to change the settings!)

Graphics: Fast (Instead of fancy)

Smooth Lighting: Off (Turn it on when you are filming to make the lighting smoother)

3D Anaglyph: Off (This doesno t apply much to the lag but leave it off unless you want 3D viewing; requires red and blue 3D glasses)

GUI Scale: Preference (This also doesno t apply to lag but I chose Automatic)

Brightness: Preference (This is your choice but I choose Bright (max) so I can see more at night)

Particles: Minimal (This doesno t reduce as much lag but is still recommended) NOTE: Some redstone devices that use smoke or water particles will not work when you have this at minimal. (This shouldno t apply to you if you dono t use redstone).

Render Distance: Normal, Small, or Tiny (Changing it to the Far setting is only recommended if your computer can handle far rendering which allows you to see farther but increases lag. Short and Tiny settings reduce a lot of lag but dono t allow you to see as far and will lag a bit when you start to walk in unrendered areas.

Performance: Max FPS (This setting allows more frames to move = smoother and faster movement. But this setting uses more power (not too much). The other settings reduce the amount of frames per second (FPS) = a bit laggier but uses less power).

View Bobbing: Preference (This doesno t interfere with lag and just moves your character so ito s more realistic).

Advanced OpenGL: On/Off (This improves your FPS rate only if your graphics (video) card supports it. Choose the On setting, and test your FPS in a Minecraft world. Change the settings back and forth to see if turning it on or off makes a difference).

Clouds: Off (This removes clouds = less lag)

After changing all these settings, you should get this:


Section 2 o Difficulty Makes a Difference

The difficulty does matter when it comes to lag. Difficulty settings allow the spawning of mobs, easy (less spawning), hard (more spawning). The more mobs there are, the more lag there is. As long as your difficulty is on Peaceful, you should feel less lag. I know that some maps and playing Minecraft survival must be on Easy or harder so ignore this tip if you have set it to Hardcore or playing MC survival, or playing a map with mobs on it.

Section 3 o Controlling Your Computer

A typical day playing Minecraft (you can skip this part unless you want to read it; ito s not as important):

So ito s the weekend and you want to finish up your play-through of a map. You turn on your computer normally and open up Minecraft and a couple other programs. When you start playing Minecraft, it suddenly lags a lot. There are a couple reasons for this:

(You can start reading this part; ito s important)

1. Your computer is old

This is often a problem for many users since their computer is older and cano t take all the o energyo from all the programs running. I recommend backing up any important files to an external hard drive (flash drive, heavy duty drive, or CD). Then, I would buy a standard computer (roughly $500-1000) and set it up. Leto s say you're a kid and you can't buy it. So just ask for it for your birthday or save up some $. I recommend computers with a substantial amount of RAM: 4 GB or more. Minecraft uses very little but adding more RAM can help. Then, add in all your files from your external drive and you're ready!

2. Your internet connection is slow or you have too many programs running at once

Situation 2
This is also a very common problem. If you know that your connection is slow, ask or call your ISP (Internet Service Provider) for an upgrade on your internet service. If you are a kid (and chances are that you are one), ignore this. Having too many programs running at once can also slow down your Minecraft. Having MS Word, Windows Task Manager, a YouTube video, and updating your computer all at once while playing Minecraft is not so good for smooth gameplay. Having one or two programs run at once is better and no programs running at once (except Minecraft) is the best.

3. You have too many programs installed or processes running (This is different than too many programs running at once)

Situation 3

Having tons of games or programs installed slows down your computer and Minecraft. If you plan on installing a bunch of programs from your computer make sure you follow these guidelines:

1.) Make sure you dono t use it anymore

2.) Google the program to make sure ito s not important for your computer to run

3.) Make sure anyone else does not use it (Shared computer between users)

If you dono t know if the program is important for your computer to run, ito s best not to uninstall it.

If you close a bunch of programs and uninstalled the programs you dono t need and still experience lag, restart your computer. You should also open Windows Task Manager and choose the Processes tab to check which processes are using the most power. Do not stop any needed processes for your computer to run.


4. Your computer is infected with a virus or malware

Situation 4
If you know your computer is infected with a virus, back-up any important files, change passwords for sites, and download/buy an Anti-Virus Program. If you dono t know if your computer is infected or not, download Lavasofto s anti-virus program (30-day trial) LINK or Avast Anti-Virus, another If your computer is relatively new (Windows 7) then you should have Norton Security (30-day trial) on your computer. Beware of unusual pop-ups and sites where they tell you that you have a virus. Also, do NOT use MyCleanPC.com since it installs a virus. However, buying an anti-virus program is easier since it does more and doesno t bother you (Your trial runs out in X days, buy o this programo now!).

Section 4 o Mods and How to Control Them

First off, you may have a couple mods installed already (TMI, SPC etc.) You are probably wondering: How does this improve my Minecraft? Well, having too many mods on Minecraft causes your Minecraft to take longer to open itself. There are a couple mods to control your performance. One is Single Player Commands. It has a o killallo command that eliminates entities such as mobs, paintings, minecarts, and tossed items. Warning: It will destroy those entities from your world so prepare if you see your paintings gone or your chicken farm deserted. An very, very good mod is Optifine. This mod increases FPS rate and decreases lag. It opens up a lot of graphics settings and render options for you to change such as particles, chunk updates and more.


Also, installing shaders causes a lot of lag. Shaders are good for cinematics but are horrible for normal gameplay and create lots of lag. Try to reduce using shaders unless needed or disable them. Installing HD texture fixes can also increase lag. When choosing a texture pack that has lots of detail (16x16 or larger), it takes longer for Minecraft to change every block and texture in Minecraft and also to render it.

Section 5 o TNT and Redstone Tips

This is very important for heavily redstone uses and TNT detonations. When TNT detonates, it breaks blocks and turns a portion of them into block entities. In the current update, same items will join together as "groupings" to reduce lag. Having tons of block entities (like 4000) will lag your computer and the explosions create lag as well. Reduce the lag by using the Single Player Command: drops. By disabling o dropso , items will not drop from TNT explosions and destroying them. As of the current Minecraft update, the command, "/gamerule doTileDrops false" will stop drops from blocks (such as TNT explosions). This also means that when you break a block in survival, it will not drop the block. Redstone contraptions can also lag your computer. Try reducing the amount of redstone and remove redstone clocks. Having redstone run at a certain time and then turned off is optimal for multiplayer servers and redstone-based mini-games. Use pistons to control the turn on/off of redstone clocks.

Section 6 o Other Tips

Turn off the Aero effect on PCs (Windows 7)

Disable screensavers, desktop effects, etc.

Allocate more RAM to Minecraft

Section 7 o Player Tips

You_Mine_I_Craft o If you have a higher-resolution texture pack, it will lag your game because of the detail and pixels it has to display. Using a lower resolution pack (16x16, 8x8, 4x4, 2x2) is better and increases your frame rate. The simpler the texture pack is, the more FPS you can obtain.

Noobkackboon o Optifine has two OpenGl modes: Fast, Slow, and Off. These modes can increase the FPS only if your graphics card supports OpenGL 2.0 or higher. Use CCleaner LINK to remove temporary files and browser history to speed up your computer. Use Windows Task Manager to o killo processes that use up the most energy (dono t kill the processes that the OS needs). Defragment your computer to speed it up. The more often you defragment it, the less time it takes. Dono t use Microsofto s defragmenter, ito s bad.

Dusty012 o In Optifine, go to video settings, then graphics and choose the graphics setting. Change it to o fasto .

Scotlickify o Allocate more RAM to Minecraft

IXLKIDDO - Install OptiFine Standard first, next install OptiFine Smooth (if smooth isn't out yet then use light), next install OptiFine Light (note if you installed OptiFine Light already in the previous step then skip this one), and last but not last install OptiFine Ultra if possible. Also install Fishtaco's FPS++ mod. LINK

Section 8 o The Bottom Line

Change your graphics settings down

Change your difficulty to stop hostile mobs from spawning to reduce lag

Make sure your computer is not old, is not infected with viruses, or running with too many programs at once

Use mods that you really need and install Optifine (compatible with most mods) and dono t install shaders (unless you need it)

Dono t use/place too much TNT and control the redstoning (dono t use redstone clocks too much)

Turn off the Aero effect and disable screensavers and desktop effects

I use only two mods (DecoCraft 2 & Chisel and Bits) and it's extremely laggy just loading in a regular world. It's even worse with a downloaded map. I also just got this computer, so what should I do? I don't want to get rid of these mods.
change your in-game resolution to 1280x720 in the launcher settings!
this is a must if you are struggling with lag. I found this helpful
while i messing around with my launcher settings.
i tested with chocaphic 13 shaders and it work smoothly.

2: Buy a new computer
3: ???
4: Profit

NO! It Increases Frame Rate when you change the graphics to fast and all you can see that is fancy turn it to fast and it will increase your frame rate like 50 more fps but you frame drop when you build a cow farm with many cows and it will lag also with a map full of redstone thingy

If you want even more FPS than you should follow these steps below:

First, go to your Search Bar (the one for your computer NOT Google, Bing , etc.)

Next, seach Task Manager and click on it.

After that, go to the Processes tab, scroll down until you find these exact words: Java(TM) Platform SE binary and then right click it. Find Go to details and then click on it.

Next, out of all of the things that you see you will only have to find one. Right click these exact words: javaw.exe.

Finally, click on Set Priority and change your priority to High or Realtime.

So, to break it down, Search Bar - Task Manager - Processes - Java(TM) Platform SE binary - Go To Details - Javaw.exe - Set Priority - High or Realtime

NOTE: This isn't a one time thing sadly.... you will have to do this every time.

If this doesn't have a significant effect on your FPS then I recommend downloading optifine here: https://optifine.net/downloads


Do shaders work? I have usally 1-2 Fps

If you have 1-2 fps without shaders there is absolutely no chance that your computer will be able to handle this. I recommend getting a new computer (4GB of RAM or higher) or just restoring your computer to factory settings.
Tripling my fps means 6 fps

I am trying this. I NEED MINECRAFT TO STOP LAGGING! When I play a LAN world, the most FPS I get is 5.
heres an idea

Your computer isn't able to handle minecraft, you might wanna get a better one xD (or completely factorize your computer so its like you just bought it from the store, can improve fps pretty well, i used to only get 30 now i get at least 100 fps xD)

(oh also, theres a settigns that will let you allocate more RAM to minecraft if you havent tried that)
I get 120 fps< with maxed graphics and full antialiasing, Full Hd and shaders LOL
Congrats you have a decent computer.


If you were trying to 1up me it doesn't really matter lol.
The only time I commonly get lag is from entities on the ground (ex. cobblestone, pickaxe, sapling). I dont understand why this is happening to me now but it wasnt a long time ago. When I'm playing TIMV on the HiveMC server, you die and drop tons of items, but that doesnt make me lag. Sometimes when I play single player and mine redstone or chickens lay eggs, i get maybe a 1 fps decrease, but anything else drops my fps by 20. I'm so confused, can someone please explain?

Or wait for 1.8. In 1.7, all the caves in loaded chunks are also being rendered when you cant see them, along with other things. In 1.8 though, it will only load things you can see. As long as you're good with looking at the floor forever, your fps could even triple!

I may try this. But I don't even need it, my frames never go below 120. Ever. But more is better ey?
This kinda worked for me,got around 15-40 FPS,but when i record it falls off to 1-3 FPS,but when i installed Advanced System Care 7,it all went good,FPS when i record is 15-40! Thanks for the post anyway,it helped,diamond 4 you :)
Didn't work, I still have random lag spikes and constant 10fps after changing all of my settings to the fastest possible (i have optifine too so thats loads of stuff that's been changed)

I also suggest using a flash drive for Ready Boost, it helps out A LOT!! I got ~55 FPS increase!

Sorry this is an old blog and I have tons of extra tech stuff I can do but see below.
Just a recap:

1.) Install Optifine and adjust options again
2.) Try defragging your computer (use Smart Defrag 2, I use it)
3.) Use CCleaner to clean your system
4.) Change what starts up on your computer using CCleaner (start-up programs)
5.) Clean your computer (inside), your computer hurts from all the dust and heat over time
Please make sure that your computer is not extremely hot and/or dusty.
6.) Make sure you are not running tons of programs at the same time.
7.) Make sure that whatever Minecraft stuff you are playing is not extremely laggy (such as an extreme redstone map/game or a TNT explosion cannon)

If this doesn't help, comment again! :D

Don't set it to max. Set up "Maximum Performance/Max FPS", Graphics - Fast, Particles - Minimal, Render Distance - Normal or smaller

I've been taking a long break from Minecraft so this might not be helpful.
