Frame rate

Frame rate (also known as frame frequency) is the frequency rate at which a video device produces unique consecutive images called frames. Frames are still pictures that when sequence together form a fluid animation that is the basis for all moving media. Frame rate is most often expressed in frames per second (FPS).

Low FPS will result in a "choppy" gaming experience, as far as looking like a slideshow in extreme cases. Difficult calculations (like blowing up huge loads of TNT in Minecraft) can temporarily decrease the FPS to a complete stop for some seconds.

How to check your FPS

 * Press to bring up the Debug screen. Frames per second are listed after the Minecraft version at the top left. (Note: The debug screen is known to cause more load to your system, resulting in a lower FPS than you would have without viewing the screen.)
 * Bring up the Options screen (press ), select Snooper Settings, and look for 'fps'.
 * Various mods have options to show the FPS without other Debug screen information.

In Minecraft
Most of the following suggestions are configurable in the game's Options menu, accessible by pressing.


 * Turn down your render distance. (default keys: + )
 * Set graphics from Fancy to Fast.
 * Turn off smooth lighting and clouds.
 * Set particles to minimal.
 * Set the game to full screen mode; this makes Minecraft the only window being loaded, making the game run a little bit faster.
 * Disable sound effects. This is particularly effective when near a large amount of sound-producing blocks (lava, flowing water) or mobs. The downside is that you could only detect hostile monsters if you can see them.
 * Hide the HUD by pressing.
 * Looking at the sky has also been known to increase FPS. However if you are deep underground, looking down toward The Void may also.
 * If in multiplayer, hold down . This will show the online players. The more players, the more lag there will be, so this could be a problem. Note that this is mostly network lag rather than FPS processing. Try playing on singleplayer.

Outside of Minecraft

 * On Windows, open Task Manager and go to the processes list, find javaw.exe (the Minecraft program), right click it and set its priority to high (NOT realtime. This will cause all other programs to crash.)
 * Put the .minecraft folder on a solid-state drive so that the world and the game itself can be loaded faster.
 * Do not run other programs while Minecraft is open.
 * Turn off Aero in Windows Vista/7.
 * Disable compositing (sometimes called "desktop effects") on GNU/Linux (Compiz, Kwin, Xfwm, etc.)
 * Update graphic card drivers and make sure antialiasing and anisotropic filtering are turned off in the driver settings.
 * Find ways to cool down your computer, this case is more rare but happens to some computers, mostly laptops. High temperatures (usually 80°C or higher) will cause the hardware to throttle, thus slowing down the game.

Third party methods
These mods are not guaranteed to work and may contain malicious files or corrupt your Minecraft program. Be careful when downloading and installing them.
 * OptiFine is a mod which can substantially speed up and stabilize Minecraft's framerate. It has now been combined with Optimine
 * There are also guides available on how to manually increase FPS by editing various files in your system.
 * Not exactly a mod, but using a ramdisk greatly improves the performance of Minecraft by storing the save files in RAM, which is much faster than a hard drive. However, there is some risk involved, if the computer crashes, you will lose all progress since your last backup to the hard drive.

Render distance
The render distance controls how many chunks of the world are visible at once, and can be set from the Options menu. The fewer chunks that are included, the faster each frame can be rendered, resulting in a higher FPS. The available distance settings, from nearest to farthest, are “Tiny”, “Short”, “Normal”, and “Far”.

The most distant terrain is faded into the sky color as if by fog, to avoid a sharp edge to the visible world; so this option is also known as "fog".

'Note: diameter = radius × 2 + 1''

As of Beta 1.8, Render distance is now a part of the environmental void fog seen as the player approaches bedrock and The Void. At layer 27, the far render distance drops to normal, and normal to short. Void fog progressively closes in at layer 13 and below. At layer 1, the void fog begins just outside of your reach, and torches are ineffective for vision though still effective for mob stopping power. Bringing sunlight (block-based light such as torches does not affect the gloom effect) to the low layers removes this gloom effect. However, this "render distance" is only fog - it will not load less chunks, resulting in little to no FPS increase.

As of 11w48a, void fog is no longer present in Creative Mode.

Video
Note:Far render distance increases your viewing level to 256 blocks, not 236 as stated in the video.
