Tutorials/Improving frame rate
Frame rate (also known as fps) 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 large amounts of TNT or spawning in a large number of mobs) can temporarily decrease the fps to a complete stop.
Monitoring frame rate[edit | edit source]
Note that your displayed fps might not be accurate, as the game has to render all of the information in the debug menu, so you may get an increase as soon as you close the display.
- Press F3 to bring up the Debug screen. The frame rate is shown under the Minecraft version at the top left. (Note: The debug screen is known to cause more load to your system, resulting in lower fps than you would have normally.)
- Bring up the Options screen (press Esc), select Snooper Settings, and look for 'fps'.
Increasing frame rate[edit | edit source]
Most of the following suggestions are configurable in the game's Options menu, accessible by pressing Esc.
- Turn down your render distance.
- Set graphics from Fancy to Fast.
- Turn off smooth lighting and clouds.
- Set particles to minimal.
- Set mipmap levels to minimal.
- Set the game to small screen mode, as this makes the game load less on screen, making the game run a little bit faster. However for computers which have a better graphics card, change your settings, so Minecraft is in full screen mode, this makes the GPU focus more on Minecraft and less on other programs. Test both ideas and see which setting works best!
- Also note, close any programs in the background and close any internet browsers.
- If in multiplayer, move away from areas densely populated by players.
- Enabling VBOs may result in higher fps.
Outside of Minecraft[edit | edit source]
- On Windows, open Task Manager and go to the processes list, find
javaw.exe(the one the game uses), right click it and set its priority to high (not realtime).
- Make sure you have enough RAM available (in a program such as a task manager), else your computer may swap to disk, which could cause the game to stutter intermittently.
- On laptops and most pre-built desktops, uninstall bloatware.
- Do not run other CPU- or GPU-intensive programs while the game is open.
- On Windows Vista through Windows 10, disable graphical effects such as Windows Aero and taskbar transparency.
- Disable compositing (sometimes called "desktop effects") on GNU/Linux. When compositing is disabled, all window managers tend to give similar performance, so there is no need to use a "lightweight" one.
- Update graphics drivers.
- Disable anti-aliasing and anisotropic filtering are turned off in the driver settings.
- Ensure the computer is running at a cool enough temperature so as to not cause thermal throttling. This is especially true for laptops and older desktops.
- Reduce the display resolution.
