How To Optimize Computer To Run Minecraft

Are you looking for ways to optimize your computer to run Minecraft faster?

If you have been playing for a while then you know a slow computer can impact a lot your performance in the game.

So, you can either buy one of the best laptops for Minecraft or just upgrade some of the hardware in your current one.

If updating or optimizing your computer is what you are looking for then keep on reading for some useful suggestions.

How To Optimize Computer To Run Minecraft

1. Increase Your Ram

One of the main things you can do to optimize your computer to run Minecraft faster or pretty much just improve your computer performance is to upgrade your RAM.

Minecraft minimum requirement to run is 2GB of RAM, we usually suggest having 4GB but if you can upgrade your RAM to 8GB it is sure your computer performance will improve highly.

This is one of the most important things to do if you want to avoid Minecraft slowing down your computer and any problems when playing the game, your RAM is going a long way here.

2. Change JVM Arguments

If your RAM is already at 8GB or more and Minecraft is still slow then it might be because the total RAM allocated for Minecraft is low.

This is an option you can change on the game settings.

To increase allocated RAM for Minecraft go to:

  1. Minecraft Right Top Menu
  2. Launch Options > Advance Settings > Add New
  3. Enter a new name for your Launch Settings
  4. Click on JVM arguments
  5. Change the “Xmx2G” into “Xmx4G”
  6. Save
  7. Start Minecraft with your new saved launch settings

Remember this option will work only if you have 8GB or more of RAM. You can’t enable this with lower RAM in your computer.

3. Upgrade The Graphics Card

The Graphics Card is another of the main hardware elements you can upgrade to make Minecraft run faster.

It is recommended to have one of the following GPUs: Intel HD Graphics 4000, AMD Radeon R5 series, NVIDIA GeForce 400 Series or AMD Radeon HD 7000 series.

If your computer has a GPU with lower specs than any of those then replacing it to a newer better one will definitely help your game to run faster.

Just make sure the new GPU you want to get is compatible with the rest of the hardware in your computer.

In the case your GPU is one of those or even more powerful than them, then check out if there is any updates on its drivers, old drivers can decrease your GPU performance.

4. Close Other Programs Running

This is a basic recommendation to make any computer run faster.

There are lots of programs in your computer that, even without you knowing, might be running in the background.

Check them out with Ctrl + Shift + Esc to see the full list.

If there is any program running that you recognize and you know you don’t need it then you should “End Task” on them.

5. Update Your HDD to an SSD

Another common piece of hardware you can upgrade that will make any computer run faster is updating your HDD to an SSD.

Be careful with this change since it is a major change in your computer. You are pretty much changing your computer’s “memory”.

You will need to install again all the software you have installed already, including the OS and Minecraft.

This is a good solution if you are thinking of using an old computer to play or just want to overall improve your computer capacity.

Similar to changing the RAM you might need an expert to help you do this if you are not a computer hardware specialist.

6. Get A New Computer

If you tried the basic steps on this list and you think it is not enough or don’t want to deal with any of them then getting a new computer might be the best option for you.

Yes, this is the most expensive option of them all but long term is the best one.

Unless your computer is not super old, then you should probably look into getting a newer one. It will improve your Minecraft performance and overall computer experience.


We hope this blog post helped you understand how to optimize your computer to run Minecraft faster.

These were the basic and common steps but there are other things you can try like the Optifine mod which was made to optimize Minecraft. Or any other similar mods too.

If it did, then please don’t hesitate to share this article with anyone you know who has an old computer and is trying to make it better for the game.

Thank you for reading.
