The suite

Nine tools. One launcher.

Every tool follows the same discipline: scan first (read-only), show you exactly what will change, back it up, then apply. Numbered in the order the guide walks you through them.

01
Program Installer
FREE
One checkbox list for everything a fresh gaming install needs — GPU drivers, launchers, Discord, benchmarking tools — batch-installed with per-item logs.
Batch install
02
GPU Overclock
PERSONAL
Installs Afterburner, detects your GPU vendor (NVIDIA and AMD), applies a safe overclock profile and fan curve tuned to your card.
NVIDIA + AMD
03
NVIDIA Setup
FREE
Applies proven NVIDIA Control Panel settings and an inspector profile — low-latency mode, power management, the details most people miss.
Driver tuning
04
CoD Settings
FREE
Recommended or benchmark graphics presets for Call of Duty with optional ReBAR — and it backs up your player profile before touching it.
Profile backup
05
Input Device Optimiser
FREE
Pick your controller, mouse and keyboard. Dedicated interrupt cores, MSI mode, USB power tuning, 1:1 mouse response and larger input queues.
Controller + M&K
06
Interrupt Optimiser
PERSONAL
Routes GPU, USB and network interrupts onto dedicated CPU lanes with MSI mode and RSS tuning — with a full backup and restore.
Full restore
07
Network Optimiser
PERSONAL
TCP stack, adapter power, MMCSS and DNS tuning — measured with before/after latency, jitter and loaded-latency tests so you see the difference.
Before/after tests
08
Debloater
FREE
Strips telemetry, ads and optional bloat with Lite and Aggressive profiles, takes control of Windows Update. LTSC-aware, fully restorable.
Lite / Aggressive
09
Game Optimiser
FREE
Game DVR off, fullscreen optimisations off, a read-only BIOS advisor (XMP, Secure Boot, PCIe, VBS) and PresentMon FPS capture to prove the gains.
Measured results

Building PCs from scratch? The Commercial plans add the full from-scratch build kit:

Partition Creator
A labelled DO NOT DELETE partition keeps your files safe across reinstalls.
MB Drivers
Detects your motherboard and fetches the right drivers from the manufacturer.
File Downloader
Stages programs, drivers and tools onto your keep-drive ahead of the reinstall.
Install Disk
Builds a bootable USB from an official Windows image — no sketchy ISOs.
Partition Merge
Reclaims leftover partitions safely after a rebuild.
How it works

Guided from first boot to final benchmark

You don't need to know what MSI mode is. The Start Here app walks you through every step in order, and the Advanced Guide PDF explains the why behind every tweak.

1
Scan
Every tool starts read-only. It inspects your system and shows exactly what it found and what it recommends — nothing changes until you say so.
2
Apply with backup
Before a single registry key changes, the tool writes a full backup. Then it applies only the tweaks you selected, logging every action.
3
Measure — or restore
Network tests run before/after latency and jitter; PresentMon captures real in-game frame times. Don't like a change? One click restores it.
Why trust it

Optimisers have a bad reputation. This one earns yours.

Most "FPS booster" tools are irreversible registry bombs, anti-cheat risks, or both. This suite was built the opposite way.

[OK]
Everything is reversible
Every tool that changes your system takes a full backup first and ships a matching restore. Round-tripped, not just promised.
[OK]
Anti-cheat & ToS safe
No kernel patching, no modified Windows images, no grey-area injectors. Official Windows ISO path and documented OS settings only.
[OK]
You see every change
Live logs show each registry key, service and setting as it's touched — timestamped, colour-coded, and kept for your records.
[OK]
Measured, not claimed
Built-in before/after network tests and PresentMon FPS capture. If a tweak doesn't help on your rig, restore it and move on.
Pricing

Start free. Seriously — most of the suite is free.

The System Scanner and the proven Call of Duty presets cost nothing. When you want lower ping and the deep tuning, Personal is a one-time $29 — never a subscription.

FAQ

Straight answers

What's actually free?
Most of it. The System Scanner, Game Optimiser with the BIOS advisor, the Call of Duty presets, the Debloater, the Input Device Optimiser, NVIDIA Setup and the Program Installer — genuinely free on one PC, no account, no time limit. Personal ($29 one-time) adds the Network Optimiser, Interrupt Optimiser, GPU overclocking, and the advanced Debloater and game toggles.
Can I use it on customers' PCs?
That's what the Commercial plans are for — Free, Personal and Family cover your own machines only. Commercial is priced per new machine: Solo covers 5 new customer PCs a month, Shop covers 25, and a PC you've already set up never counts again. Your own workbench PC is free, and if you run out mid-month the tool keeps working at Free level until your next billing date.
Will this get me banned by anti-cheat?
No. The suite only changes documented Windows, driver and BIOS-advisory settings — the same things a careful power user would change by hand. There is no kernel modification, no memory injection, and no modified Windows image. Nothing it does is visible to, or against the rules of, any anti-cheat.
How much FPS will I gain?
Honestly: it depends on your hardware and how untuned your system is. That's why the suite ships its own measurement tools — before/after network latency tests and PresentMon frame-time capture — instead of quoting made-up numbers. Typical wins are lower input latency, more consistent frame times and fewer stutters, rather than a magic headline FPS figure.
What if a tweak makes something worse?
Restore it. Every tool writes a full backup before applying anything and has a one-click restore that puts the exact previous values back. You can apply, test, and roll back tool by tool.
Do I need to reinstall Windows?
No, but it's recommended — the best results come from a fresh start, with the suite tuning a clean install instead of years of accumulated clutter. The nine main tools work fine on your existing install, and the pre-install tools make the fresh route painless: a keep-partition for your files, staged downloads, motherboard drivers and a bootable USB from an official Microsoft image.
What are the requirements?
Windows 10 or 11 with administrator rights. NVIDIA and AMD GPUs are both supported for overclocking; the NVIDIA Setup tool is NVIDIA-only by nature. The Debloater is aware of LTSC editions too.
Is this a subscription?
Personal and Family are one-time purchases — pay once, and the suite is yours forever, with 12 months of updates included. Only the Commercial shop plans are monthly, because they're priced per new customer machine.
