About
FPSFlow is a client-side Fabric mod that improves Minecraft performance by reducing rendering work, with four profiles ranging from Quality to Ultra Performance and individually configurable features. It culls entities outside the camera view, behind solid blocks, or beyond a chosen distance, and reduces the update rate for distant entities while keeping server NPCs and entities near nameplates fully rendered. Other visual optimizations hide distant name tags and block entities such as chests, furnaces, signs, banners, and item frames; limit particle counts and density by distance; and skip paintings viewed from behind. A background frame-rate limiter applies when the game window is unfocused or minimized, while the world-join optimizer gradually increases culling after joining to ease the initial performance spike. In singleplayer, more aggressive adaptive culling frees CPU capacity for chunk generation, and hotbar caching and HUD throttling reduce interface rendering work while responding to actual stat changes. Settings can be customized through the configuration, and FPSFlow automatically disables overlapping culling or HUD optimizations when it detects compatible mods such as EntityCulling or ImmediatelyFast.

No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.
- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.21.11. See Privacy
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.2 latest files: the newest file for each Minecraft version and loader. Both are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

We found nothing it sends about you
We read its code without running it: it contacts 1 web address while you play.
Like any connection, each address it contacts sees your IP address.
The author declares on Modrinth that it shows advertisements.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of both files, for recent Minecraft versions. See each file in Releases

AI
AI was used for its code, text and assets
The author declares AI code, assets and text on Modrinth.
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
