I built a free Windows 11 gaming optimizer called FPSBoostPro, and the whole point is that you click one button and get on with your game. No hunting through Settings. No copying commands off Reddit. No wondering what you just broke.
It turns off the stuff Windows runs in the background while you game, switches on the settings Microsoft buried three menus deep, wipes out temp junk, and then gives you a single button to put everything back if you hate it.
It costs nothing. There’s no paid version, no ads, no account.
Let me tell you honestly what it does and what it won’t do.
Quick verdict
What it is: A free Windows 11 gaming optimizer that applies 22 gaming and privacy settings in one click, cleans out junk files, and can undo all of it.
Price: Free. MIT licensed, open source.
Works on: Windows 11. Tested on 23H2, 24H2 and 25H2.
Needs admin: Yes, you’ll get a UAC popup.
Time to run: About two minutes, plus a reboot.
Best for: Older or cluttered gaming PCs. Also anyone setting up a fresh Windows install.
Don’t expect: A guaranteed FPS jump. More on that below, and I’m not going to pretend otherwise.
What the optimizer actually turns off
Here’s the plain English version of what happens when you hit the button.
Background recording. Windows quietly records the last 30 seconds of your gameplay at all times, in case you want to clip it. If you never clip, that’s work your PC is doing for nothing.
Xbox Game DVR. Same idea, the older version of it. Off.
Widgets. That news and weather panel on your taskbar refreshes itself in the background even when you never open it. Gone.
Transparency and window animations. The fade and slide effects when you minimize things. Small, but free to remove.
Windows power saving on your CPU. Windows likes to put “unimportant” things into a low power mode. Sometimes it guesses wrong about your game. This stops it from guessing.
Telemetry and Windows tips. The diagnostic uploads and the “here’s a suggestion” popups.
And what it turns on
Game Mode. Usually already on, but people switch it off while troubleshooting and forget.
Hardware Accelerated GPU Scheduling. Lets your graphics card handle some scheduling work instead of your CPU. This one needs a reboot.
Ultimate Performance power plan. A hidden Windows power plan that stops your CPU from dozing between frames. It’s not in Settings; you normally need a command to unlock it.
Exclusive fullscreen. Pushes games toward real fullscreen instead of the borderless window Windows prefers. Can shave a bit of input delay in older games.
Raw mouse input. Turns off “Enhance pointer precision” so your mouse moves 1:1 with your hand. If you play shooters, you probably want this. If you’ve had acceleration on for years, your aim will feel weird for a day.
You don’t have to take the whole package. There’s a tab where you can tick the ones you want and skip the rest.
Will it actually boost my FPS?
Straight answer: maybe a little, and I can’t promise it.
Nothing in this tool makes your graphics card faster. If you’re running a GTX 1070, no setting turns it into a 4070. Anyone who tells you a tweak gave them 40 extra FPS and doesn’t show you a graph is making it up.
What it does help with is the other thing, the one that actually ruins games: stutter.
You know the feeling. Your FPS counter says 90, but every twenty seconds the game hitches for a split second and your crosshair jumps. That’s usually something in the background waking up and stealing CPU time for a moment. Fewer background processes means fewer of those hitches.
So if you get a benefit here, it’ll show up as the game feeling smoother, not as a bigger number in the corner. On a clean high-end rig with 32 GB of RAM, you’ll probably notice nothing at all. On a five-year-old machine with 40 startup programs, you might notice quite a lot.
I didn’t run controlled benchmarks, so there are no FPS numbers in this article. I’d rather say that than invent some.
If your game is stuttering badly right now, it’s worth reading how to fix game lag and RAM stutter first, because sometimes there’s a specific cause an optimizer won’t touch.
What it actually cleaned on my PCs
This is the one thing I can show you real numbers for, because the tool measures it.
On one of my test machines, it cleared 5.15 GB: about 3 GB of user temp files, 2.2 GB of Windows temp, and a bit of leftover shader cache.
On the other machine, right after I’d already run the optimizer, it found 0 MB. That’s the honest answer, and I left it in the video on purpose. Any cleaner that always finds gigabytes to delete is lying to you.
It also clears your DirectX shader cache. Small heads-up on that one: the first time you launch a game afterwards, it has to rebuild those shaders, so it might stutter for a few minutes before settling down. That’s normal.
How to use it
1. Download it
Grab FPSBoostPro from the GitHub page. Click the green Code button, then Download ZIP.
2. Extract the whole folder
This is where people get stuck. Don’t run it from inside the ZIP. Right-click the ZIP, extract it properly, and put the folder somewhere sensible like C:\Tools. If you run it from inside the ZIP, the window will flash open and close instantly.
3. Double-click Run.bat
A black console window shows up for a few seconds while it loads.
Windows may show a blue SmartScreen warning saying it doesn’t recognise the app. That’s because I haven’t paid for a code signing certificate, not because anything’s wrong. Click More info, then Run anyway. If that makes you uncomfortable, fair enough; the source code is right there to read.
Then say yes to the UAC prompt. It needs admin because it’s changing system settings.
4. Check the Dashboard
It shows your CPU, GPU, RAM, drives, and current power plan. Quick note: if your graphics card shows as 4 GB when you know it has 8, that’s a known reporting bug on my side, not a problem with your card. Ignore it.
5. Hit Optimize For Gaming
It’ll ask you to confirm, then take a minute or so. It makes a Windows restore point first, which is the slow part.
6. Reboot
Two of the settings do nothing until you restart. If you skip this and decide the tool didn’t work, you didn’t really test it.
The other tabs, quickly
The one-click button is the main event, but there’s more if you want it.
Startup apps. This is honestly the one most likely to make an old PC feel better. It shows everything that launches with Windows, including Store apps that Task Manager buries, and lets you switch them off.
Services. Ten optional Windows services you almost certainly don’t need, like the fax service and the in-store demo mode. It sets them to start only when something asks for them rather than switching them off, so nothing breaks. It physically refuses to touch anything else, so you can’t accidentally kill your audio.
Debloat. Removes the pre-installed apps you never open. It will not let you remove the Microsoft Store, Windows Security, the Xbox app, or anything Windows needs. Those are locked out in the code, and they show up greyed out.
To be clear, removing Solitaire will not make Cyberpunk faster. What it removes is clutter and background update checks.
Is it safe?
Short version: yes, and more importantly, it’s reversible.
Before it changes anything, it makes a Windows System Restore point and writes down the exact state of every setting it’s about to touch. Not “what Windows probably had by default”, but the actual value that was on your PC. That means undo really is undo.
It never touches Windows Defender. It never disables Windows Update. It can’t remove anything Windows needs to boot.
The things to be aware of:
- You’ll get a SmartScreen warning because the app isn’t code signed.
- It runs as admin. It has to, since it’s changing system settings.
- Only download it from the official GitHub page. “Free FPS booster” search results are a genuinely sketchy corner of the internet.
- If your PC is actually crashing rather than just running slow, an optimizer is the wrong tool. Start with fixing the blue screen instead.
How to undo everything
There’s a tab called Restore Center with a big Restore Everything button. That’s it.
You can also undo just one category, like putting back the gaming settings but keeping the privacy ones. Apps you removed get reinstalled from the Microsoft Store automatically.
And if you want the sledgehammer, the Windows restore point it created is still sitting there.
Should you bother?
Old or cheap gaming PC: Yes. This is where it helps most. The startup cleanup and junk file removal alone are worth the two minutes.
Mid-range PC: Sure, run it. Mostly for the power plan and the startup apps.
High-end PC: Honestly, don’t expect much. If you’ve got 32 GB of RAM, an NVMe drive and a current GPU, your frame rate is limited by your graphics card and your settings, not by Windows. Use it as a tidy-up tool.
Gaming laptop: Be careful. Skip the power plan and the CPU power tweak. Laptops run hot, and telling Windows to stop saving power on a laptop that’s already thermal throttling makes things worse, not better. Use the individual tweaks tab and leave those two alone.
Competitive shooter players: The raw mouse input and exclusive fullscreen settings are the ones you care about. Apply them, play a few rounds, keep them or reverse them. Don’t change your mouse feel the week of a tournament.
You stream or record clips: Careful with the background recording setting. If you use the Windows Game Bar to clip, turning it off breaks that. If you use OBS, it doesn’t matter.
Your PC is also your work machine: The privacy tab turns off things like Copilot and Windows search suggestions. Handy for gaming, annoying if you use them for work. Skip that tab.
Pros and cons
Good:
- Actually free, no upsell, no ads
- One click, done in two minutes
- Genuinely reversible, with a real restore point
- Every setting is explained in plain English before you apply it
- Can’t break Windows Defender, Windows Update, or the Store
- Tells you honestly when there’s nothing to clean
Not so good:
- No built-in FPS test, so it can’t show you whether it helped
- SmartScreen warning on first run, because it’s unsigned
- Some of the settings are pretty minor, and the app presents them all as equally important
- Windows 10 isn’t supported
- Your graphics card’s VRAM may display incorrectly on the dashboard

My verdict
I use it on every fresh Windows install, and that’s genuinely what it’s for. There are about twenty settings I always change and always forget three of, and now I don’t have to remember.
Would I tell you it’ll give you more frames? No. On my older test rig, the realistic gain is smoother frame delivery, not a higher number. On a modern machine, you’d struggle to measure a difference at all.
What I’d actually recommend it for: you just reinstalled Windows, or your PC has been collecting startup programs for three years and feels sluggish. In both those cases, it’ll help, it takes two minutes, and if you don’t like it you click one button and it’s gone.
Windows 11 gaming optimizer FAQs
Yes. It’s open source under the MIT licence, hosted on GitHub. No paid tier, no ads, no account, and it doesn’t collect anything about you.
Maybe slightly, but there’s no guarantee and I’m not going to claim one. It mostly helps with stutter and smoothness rather than your average FPS. It cannot make your graphics card faster.
Yes. It makes a Windows restore point first, records every setting before changing it, and never touches Windows Defender or Windows Update. Everything is reversible from one button.
Because the app isn’t code signed, which costs money. SmartScreen warns about any unsigned app. Click More info, then Run anyway. The code is public if you want to check it first.
Yes. It’s changing system settings, so Windows will show a UAC prompt. Say yes or it won’t run.
Two of the settings need a reboot to kick in. The rest work immediately. The app tells you which ones as it runs.
Yes, one button in the Restore Center. You can also undo just one category, and any apps you removed get reinstalled automatically.
Not officially. It’s built and tested for Windows 11. It will open on Windows 10 and optimze the available settings. You can safely run it on your Windows 10 PC.
Yes. The walkthrough was recorded on 25H2 and the app reported it as fully compatible.
Yes, but skip the Ultimate Performance power plan and the CPU power throttling setting. Both make your laptop run hotter, and a hot laptop slows itself down. Use the individual tweaks tab instead of the one-click button.
No. It only clears temp folders, caches and the Recycle Bin if you tick that box. It never touches your documents, your game installs or your saves.
No. The Xbox app, the Microsoft Store, Windows Security and anything Windows needs are all blocked from removal in the code. They appear in the list but can’t be selected.
Big feature updates can reset some of them, and a graphics driver update can flip the GPU scheduling setting back. Just open the app and hit Refresh to see what’s currently on.
For frame rate, there’s not much point. Your bottleneck is your GPU and your graphics settings. It’s still handy as a cleanup and startup manager.
