When I had my old laptop, I could run Minecraft quite fine, even with the Amazing Shaders mod. When I got my brand new laptop, I could already imagine the possibilities. 2000+ fps. No lag. I was going to be invincible with my NVIDIA GeForce 630 M.

Or so I thought.

When I opened Minecraft and made a "Test" world in Creative, I was very happy to see how fast things were running until I saw the fps when I hit F3, 93. 93? It didn't look like 93, but I continued to fly around my world relatively smoothly. One and a half minutes later, the "exponential lag" occurred. Two seconds, one frame. Four seconds, one frame. Eight seconds, one frame. This got so bad, it took a while just to exit the game!

Is there any way I can play Minecraft fast ever again? Is it my graphics? CPU? RAM? Please help!


  • Windows 7 64 bit OS
  • Intel Core i7 Quad Core CPU @2.6 GHz
  • nVidia GeForce GT 630M 1 GB
  • 8 GB RAM

    More system information, much more system information!

    Same advice as Bobby. BTW, are your java install & drivers up to date?

  • Yes drivers are up to date (I got this baby last week) and the latest Java is installed.

    @parioscreations But did you update the drivers and Java? "Got it last week" might mean that it's using software from last year for all we know. OEMs are well-known for using out-of-date drivers and software because of scaling problems with keeping everything current. Also, if you have Java 7, uninstall it and downgrade to Java 6. Minecraft and Java 7 often don't get along. Sep 16, 2012 at 17:45

    Also make sure that your laptop and especially GPU aren't running in "power saving" mode, which is usually the OEM default setting. It could be throttling the CPU and GPU, on top of potential Java 7 and driver issues. Sep 16, 2012 at 17:49

Try Getting the OPtifine mod it adds more options and speeds up your game i have a friend who has terrible internt and when he got this mod his minecraft sped up quite a bit. It is even legal to have on servers.


First of all, try different video settings. Such as turning Fancy to Fast if it's on, no smooth lighting and render distance to minimal chunks. Just try scrolling through them and see what the effect is on your performance.

If that does not help, check your ram allocation using F3, and look in the upper-right corner of the screen. If that gets above around 70-80 %, (depending on preference) add more ram to Minecraft. (Remember you need to make sure other programs can still run without Minecraft consuming all the ram so that might be a problem)

You can do this in the profile editor under Java settings (advanced). In JVM Arguments you will see that you can input how much ram you want Minecraft to be running on. In this box you fill in:

"-Xmx2048M -Xms2048M" for 2GB ram

"-Xmx4096M -Xms4096M" for 4GB ram

To add more, add 1024 to the numbers for an extra gigabyte.

eg, 4096 (4GB) + 1024 = 5120 (5GB)

If that does not help, try deleting your .minecraft folder in it's respective location.

Mac: /Library/minecraft

Windows: Press Windows+R, type %appdata& and press Enter. Then locate .minecraft.

But make sure you back the folder up!

Many people have used this technique for similar problems without: eg. Internet connection, so the launcher could not re-download the folder. This is also the folder were world saves and texture-packs are stored so again, back it up first.

if that does not help you need to wait for new vidcard drivers that might solve the problem.
