A guide to how much is on the table, not a verdict on your PC — a low score means there’s more to gain, not that anything’s wrong with your hardware.

System Scanner
62/100
Room to improve
A decent machine with some easy wins available.
1 to remove · 1 to configure · 2 BIOS settings to change
REMOVE “Driver updater” utility — runs at boot, updates nothing you need
CONFIGURE RGB/fan software — keep it, but stop it launching at startup
BIOS Memory profile not enabled — your RAM is running below its rated speed
BIOS GPU link speed set to Auto — pin it to Gen 4
Nothing is changed for you. Every action stays your decision.

The suite

One app. Start with your score.

Every tool follows the same discipline: scan first (read-only), show you exactly what will change, back it up, then apply. Most of them are free — the badge on each card says which plan it needs.

01
PC Health Score
FREE
One number out of 100 for how much performance your PC is leaving on the table, with the reasons listed underneath and a band from Lots to gain to In good shape. Read-only — it changes nothing.
One click
13
System Scanner
FREE
Start here. Finds the software slowing your PC down — antivirus, motherboard and RGB utilities, “driver updater” junk — and gives you the best settings for what you keep. Includes the BIOS checks, in your board's own menu wording.
Read-only
02
GPU Overclock + Undervolt
FREE
Per-card starting points for MSI Afterburner (NVIDIA) and AMD Adrenalin, with the traps spelled out. Detects your card and writes a profile applied on boot.
NVIDIA + AMD
03
CPU Tuning Advice
FREE
PBO, Curve Optimiser and undervolt starting points for your exact chip, in your board’s BIOS wording — plus safe memory voltage ceilings and tREFI, the biggest single latency gain in memory tuning.
04
Game Optimiser
FREE
Turns off the Windows features that quietly cost you frames, like background game recording. Fully reversible.
05
NVIDIA Setup
FREE
The NVIDIA Control Panel and Inspector settings that reduce input lag — max performance, low latency, frame cap, ReBAR. Backs up your profile first.
06
CoD Settings
FREE
Proven Call of Duty graphics presets tuned on real machines (ReBAR / no-ReBAR). Backs up your current settings first.
07
Program Installer
FREE

Network Optimiser
PERSONAL
Lower, steadier ping for online play. Measures your connection before and after so you can see the difference. Fully reversible.
Measured
09
Interrupt Optimiser
PERSONAL
Stops your graphics card, USB and network competing for the same part of the CPU, which reduces stutter. Also switches to a high-performance power plan.
10
Input Device Optimiser
PERSONAL
Makes your controller, mouse and keyboard more responsive — removes mouse acceleration, gives your devices priority, fixes the Xbox-button popup.
11
Debloater
PERSONAL
Removes Microsoft's ads, tracking and preinstalled junk apps. Recommended (safe, reversible) or Advanced — Recommended leaves your antivirus on.
Full restore
12
Full Memory Tuning
PERSONAL
Identifies your DRAM die from SPD — which Windows can't report on its own — then gives the primary timings for your kit, tRFC, tRRD/tFAW, and what to stress-test with.
DDR5 + DDR4

Building PCs from scratch — for yourself or for customers? The Commercial plans add the 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

GPU and CPU tuning are free.

Prices are set, but nothing is on sale during the private beta.

Free tells you what's wrong with your PC and gives you the tuning most people are looking for — the scanner, the BIOS checks, GPU overclocking and undervolting, CPU tuning advice. Personal does the work for you, and goes where you'd otherwise need to know which DRAM die you have. One-time $29 — never a subscription.

FAQ

Straight answers

Can I buy it yet?
Not yet — Slightly Optimised is in a private, invite-only beta, so checkout is closed. The prices on this page are what it will cost when it opens. If you'd like to test it early, email support@slightlyoptimised.gg and tell us a little about your PC and what you play.
What is the health score?
One number out of 100, from a single read-only scan, for how much performance your PC is leaving on the table — with a band (Lots to gain → In good shape) and the reasons listed underneath: what to remove, what to reconfigure, and which BIOS settings to change. It's a guide to headroom, not a grade on your hardware: a low score means there's more to gain. Nothing is changed for you — every action stays your decision.
Where do I find help inside the app?
Every screen has a Guide button next to Report a problem, covering installation, backups, undoing changes and how to report an issue. So if you lose the email, the instructions are still in front of you. Anything else: support@slightlyoptimised.gg.
What's actually free?
Most of it, including the parts people usually pay for. The health score, the System Scanner and its BIOS checks, GPU overclocking and undervolting, CPU tuning advice (PBO, Curve Optimiser, undervolt, tREFI), the Game Optimiser, NVIDIA Setup, Call of Duty presets and the Program Installer — genuinely free on one PC, no account, no time limit. Personal ($29 one-time) adds the Network and Interrupt Optimisers, the Input Device Optimiser, the Debloater, and full memory tuning.
Is this a replacement for a full optimisation?
No. The suite automates what can be automated safely and tells you plainly what it found — but it isn't a substitute for a full hands-on optimisation, where someone works through your specific hardware, your games and your BIOS with you. Think of it as doing the well-understood work properly, and showing you where the rest is.
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.
