What is the Pie Chart in Minecraft?

The pie chart in Minecraft displays real-time profiling information for the game. It is activated by pressing Shift + F3. The pie chart shows how much time is being spent on different tasks during each frame of gameplay.

Specifically, the pie chart breaks down the percentage of time spent on various internal game processes like rendering, ticks, and chunk updates. This allows players to easily see where potential bottlenecks or performance issues may be occurring.

For example, if a large percentage of time is being spent on entity ticks, there may be too many mobs loaded in an area causing lag. The pie chart provides an at-a-glance visualization of this profiling data.

Using the Pie Chart to Find Specific Blocks

The pie chart can be a useful tool for locating rare blocks and structures in Minecraft, especially fortresses in the Nether. By displaying profiling information, the pie chart breaks down how much time is spent on different tasks each frame.

When exploring the Nether, pay special attention to the "block entities" section of the pie chart. Block entities refer to more complex game elements like chests, spawners, etc. A higher percentage for block entities may indicate that a fortress is nearby, since fortresses contain mob spawners. As explained on gaming.stackexchange.com, "By slowly increasing block entities you know you are getting closer to the fortress."

Standing near a fortress spawner will show a spike in the block entities portion of the pie chart. Reddit users recommend watching for this spike as a strategy for zeroing in on a fortress. So analyzing the pie chart percentages can help navigate and pinpoint the fortress location.

Enabling and Disabling the Pie Chart

The pie chart can be toggled on and off by pressing Shift + F3. This keyboard shortcut will enable the pie chart overlay if it is currently disabled, and disable it if it is currently enabled.

Pressing F3 alone will hide the debug screen, but the pie chart will remain visible. To completely remove the pie chart, you need to fully reload the world.

According to a Reddit user, the pie chart can sometimes get stuck on the screen. Even leaving the world and going back to the main menu may not get rid of it. A full reload of the world is necessary to completely reset the pie chart overlay.

Customizing the Pie Chart Display

The pie chart display can be customized in Minecraft to show more detailed profiling information. By pressing the number keys 1 through 9 while the pie chart is open, different levels of detail can be accessed.

For example, pressing '1' shows just the high-level categories like render and tick. Pressing '9' shows extremely detailed profiling that breaks down timings for every single game system and function.

Making the GUI scale smaller in video settings is another way to enlarge the pie chart display on screen. However, the pie chart does not actually scale proportionally with the GUI size. So it can still be difficult to read at times.

As noted on the Minecraft Wiki Fandom site, "The pie chart doesn't scale with GUI scale, meaning that even with the smallest GUI scale the pie chart can be extremely tiny and hard to read" (source).

Pie Chart on Multiplayer Servers

The pie chart can be controversial on multiplayer servers. Some server administrators want to restrict its use to only operators (OPs), as it provides players an advantage in finding rare blocks and structures like Nether fortresses. According to a discussion on the Minecraft Feedback site, "Let the server decide if this small advantage is acceptable or not."

However, the pie chart can also help server admins identify performance issues. As noted on r/admincraft, the debug information provides useful metrics like tick times and areas causing lag. So some admins may want to keep the pie chart enabled for profiling purposes, while limiting its use by survival players.
