Twelve modules for smoother frames, sharper visuals, cleaner input and clearer audio, tuned across your whole Windows setup. One click, fully reversible.
Colour is handled between the game’s output and your panel rather than inside the game. Gamma, contrast and digital vibrance are set at the driver, and the display’s own profile is corrected to match, so the darkest part of a scene separates into distinct tones instead of collapsing into one flat black, while the bright end stops short of clipping. Because it sits on the display pipeline, the same profile holds across every title you play.
Touches / 対象
Driver colour profile: gamma, contrast and digital vibrance
Windows display ICC profile and the calibration ramp loaded with it
Panel scaling mode and desktop colour depth on the active output
Colour-format and range handshake between the GPU and the monitor
Never touches: the game client, its files, or its memory.

Input Optimizer
The goal is regularity rather than raw speed. Device reports normally arrive in clusters, a burst then a gap then another burst, because the polling interval, the report buffer and the system timer are each doing their own thing. Setting them together evens out the gaps, so pointer movement is delivered on a steady schedule and the curve Windows applies to it stays predictable from one session to the next.
Touches / 対象
Device polling interval and the HID report buffer size behind it
USB selective suspend and per-port power management on the input controller
Windows pointer-precision curve and pointer scaling
System timer resolution and the scheduling priority of the input thread
Never touches: the game client, its files, or its memory.

Network Stabilizer
A connection that is fast on average can still arrive unevenly, and it is the unevenness you feel. A local QoS policy gives the game’s traffic priority ahead of everything else leaving the machine, the adapter buffers are sized so packets are not held back waiting to fill a batch, and the small-packet delays built into TCP are switched off. The result is a narrower spread between packets, not a different route.
Touches / 対象
Local QoS policy marking and prioritising the traffic of the running title
Adapter receive and transmit buffer sizing, and interrupt moderation
Nagle’s algorithm and TCP delayed-acknowledgement behaviour
DNS resolver selection and the behaviour of the local resolver cache
Never touches: the game client, its files, or its memory.

Frame Pacing
A high average frame rate made of wildly different frame times reads as worse than a lower one delivered evenly. This module goes after the variance: the power plan is stopped from parking cores mid-session, GPU scheduling and the present path are set so frames reach the display on a regular cadence, and the background work competing for the same cores is quietened. The target is a flat frame-time line, not a bigger peak number.
Touches / 対象
Windows power plan, processor idle behaviour and core parking
Hardware-accelerated GPU scheduling and the driver present mode
Background process and service load for the duration of a session
Shader cache size and the per-application driver profile
Never touches: the game client, its files, or its memory.
保証 / Assurance
Fumetsu does not interfere with the game client. It works on driver, display, input, audio, network and Windows settings.
Every change is reversible. Nothing is made permanent.
It optimises Windows and in-game settings.
無料 / Limited · $0
Feel the difference for $0. Unlock all twelve when it earns it.
Limited runs Visual Clarity, basic input tuning and Safe Restore: no card, just a free account verified in our Discord, one click on Windows. When you want Frame Pacing, Display Sync, audio, memory and the rest of the twelve, Premium unlocks them on the same install.
Fumetsu sits beside the game rather than inside it, so nothing it does is one-way.
接続・設定・性能
01
Install
接続
Start on Limited for $0 with no card, join our Discord for a free month of Premium, or buy Premium outright. Either way it is one installer, and your plan decides what switches on.
02
Settings
設定
Choose a profile for the title you play. Fumetsu reads how your Windows, display, input and audio are set up before it writes anything new.
03
Performance
性能
Play with even frame delivery, cleaner input and clearer audio. One control puts every original value back exactly as it was.
Setup takes a few minutes. Start on Limited, and move to Premium on the same install when you want the whole suite.
Premium is a one-time payment per package - by card, Apple Pay, Google Pay or crypto: 30 days, 150 days or lifetime. Buying again while Premium is active adds to the time you have left. See the refund policy; billing questions are handled by the team in the Discord.
質問 / FAQ
Straight answers, including the awkward one.
If something here is still unclear, ask in the Discord.
Will this software get me banned?
Fumetsu runs outside the game. It does not read or write game memory, it does not inject into the game process, and it does not modify game files. It changes Windows, driver, display, input, audio and network settings you could also change by hand. Anti-cheat policy is set by each publisher, so check the rules for the title you play if you are unsure.
Which games does it work with?
CS2, Valorant, Apex Legends and other FPS titles. The tuning applies to Windows and your hardware, not to a game, so it is not tied to one game client.
Do I have to undo anything myself afterwards?
No. Every setting Fumetsu touches is read and stored before it is changed, and one control puts all of it back. Nothing it writes is meant to outlive the session.
What is the difference between Limited and Premium?
Limited costs $0 and needs no card: Visual Clarity, basic input tuning and Safe Restore. Premium unlocks all twelve modules - Frame Pacing, Display Sync, Audio Positioning, Background Control, Memory & Storage, Peripheral Profiles, Network Stabilizer and the rest - plus per-title profiles, session telemetry and priority support. It is the same install; the plan on your account decides what switches on.
Can I try Premium for free?
Yes: your first month is free. Create a free account, join the Fumetsu Discord and link it from your console, and Premium switches on for 30 days with every module unlocked. No card, nothing to cancel. It is one free month per person and per Discord account, the Discord account must be at least 30 days old, and it stays on while you are in the server. Details at fumetsu.cc/free-premium.
How does paying for Premium work?
Pick a package: 30 days, 150 days or lifetime, and pay once on a secure hosted checkout - by card, Apple Pay, Google Pay, or in stablecoins (USDC/USDT) from any wallet or exchange. Your card and wallet details never touch this site. Premium switches on as soon as the payment is confirmed, usually within a few minutes. Nothing renews on its own, and buying again while Premium is active adds to the time you have left.
Where do I get help, or ask about a refund?
In the Discord. Setup help and billing questions are handled there by the people who work on the tool. Refunds follow the refund policy linked at the bottom of every page.
