Max Framerate
Want to enhance your performance in Minecraft Pocket Edition? Consider using the mod called Max Framerate for Minecraft Pocket Edition, which leverages a hidden feature in Minecraft PE 0.17.0.1 beta to boost FPS (frames per second) to its highest potential or to values set by the player. You can increase or decrease the FPS. Increasing FPS is beneficial on more powerful devices, while lowering it may be useful for players with less capable hardware or for conserving battery life, which can also aid gameplay in MCPE. Although this is an experimental feature, you can use it in MKPE without encountering any issues.
