Dynamic FPS Mod FAQ

It automatically lowers your frame rate, volume, and popups when the game window isn't the one you're actively using. When the window is hidden or minimized it can stop rendering entirely, freeing up CPU and GPU for whatever else you're doing.

Once installed it works out of the box with sensible defaults, so you don't need to do anything to get the basic benefit. To change behavior, open the mod's config screen from the mod list and adjust the frame rate, volume, and idle timer options for each window state.

Open your mod list, find Dynamic FPS, and click the config button next to it. The settings are grouped by situation, so you can set separate values for unfocused, minimized, invisible, idle, and battery-powered states.

The mod only kicks in once it detects the window state change, and some setups report the window as focused even when it isn't. Check that the mod is actually enabled in your mod list and that the unfocused frame rate limit isn't set to unlimited.

Yes, but be careful with aggressive settings. If you drop to a very low frame rate or stop rendering while on a server, you can miss chat, get disconnected for appearing idle, or fail to react to mobs, so keep a reasonable limit for unfocused play.

It can, because capture software often reads the game window even when you're not looking at it. If your recording goes black or stutters when you tab away, raise the unfocused frame rate or disable the mod's rendering stop for that window state.

The idle timer watches for a period without input and then applies your chosen settings, such as lowering the frame rate or pausing rendering. Any keyboard or mouse activity resets it, so it won't trigger while you're actually playing.

Enable the battery-powered option in the config and choose lower frame rate and volume values than your normal settings. The mod detects when the device switches to battery and applies those values automatically, then restores your normal settings when you plug back in.

Yes, there's an option to display battery status in the interface. Turn it on in the config if you want to see the current charge level while playing.

It improves performance for everything else running on your machine, not for Minecraft itself while you're playing. The gains show up when the game is in the background, which is useful on low-end systems, laptops, and when running other apps alongside the game.
