**What this mod does**<\/p>\n
Perf Boost adds a **stats HUD** in the top-right (toggle with **P**) showing FPS, frame time, RAM usage, entity and chunk counts, ping in multiplayer, and CPU usage\/temperature when available. It also adds **performance mode** (toggle with **O**): when enabled, the mod temporarily lowers your graphics settings to improve FPS, and restores them when you turn it off.<\/p>\n
**What performance mode changes**<\/p>\n
When you turn performance mode **on**, the mod temporarily applies:
\n– Graphics \u2192 Fast | Particles \u2192 Minimal (and caps active particles at 2,000) | Render distance \u2192 8 chunks | Simulation distance \u2192 6 chunks | Entity distance scaling \u2192 0.5 | Ambient occlusion \u2192 off | Entity shadows \u2192 off | Biome blend \u2192 0<\/p>\n
When you turn it **off**, your previous settings are restored. Nothing is written to your options file; it only affects the current session.<\/p>\n
**Why use it**<\/p>\n
– See FPS and system stats at a glance without leaving the game.
\n– Get a quick FPS boost in busy areas (e.g. lots of entities or particles) by pressing O; turn it off when you leave.
\n– Keybinds (P and O by default) are rebindable under **Perf Boost** in Options \u2192 Controls.<\/p>\n
