A 144 Hz monitor running at 60
Windows does not always use your monitor's maximum refresh rate. You paid for a fast monitor and play seeing fewer frames.

What holds your FPS back
Often the problem is not your PC. It is Windows set up for something else
These are cases the PC Scan finds often. None of them shows up on screen until someone goes looking.
Laptop using the integrated GPU
On laptops with two graphics cards, CS2 can open on the weaker one. The FPS difference is usually big.
Balanced power plan
It lowers the processor clock when it thinks it is not needed, and the drops show up right in the middle of a fight.
Background recording turned on
Xbox Game Bar can keep recording the last minutes of gameplay all the time, using GPU and disk.
How it works
From diagnosis to testing, in four steps
Nothing is hidden. You see what each tweak does before applying it and check afterwards that it is still there.
PC Scan
Checks monitor, power, graphics card, memory and Windows, and sorts problems from biggest to smallest impact.
Pick a mode
Safe, Competitive or Low-end PC. Each tweak shows what it does, its risk and whether the gain is proven.
Optimize with a safety net
Before changing anything, CSBoost creates a Windows restore point and saves the previous value of every tweak. In History, each one has a Revert button.
Measure before and after
The benchmark measures average FPS, 1% lows and stutters while you actually play. If it did not improve, you undo it.
Sample data
Rule #1
Built to never put your account at risk
CSBoost changes Windows and the config files you could edit yourself. The game, never.
What CSBoost does
- Adjusts Windows settings: registry, power plan, monitor refresh rate.
- Creates a restore point and saves the previous value of every tweak.
- Writes
autoexec.cfgonly when you ask. - Measures FPS with PresentMon, Intel's official tool that reads events from Windows itself.
What it never does
- Open, read or write the memory of
cs2.exe. - Inject code or draw overlays inside the game.
- Change game files other than your
.cfg. - Suggest
-allow_third_party_software, which turns off Trusted Mode.
This rule is locked into the code: the build fails if any process-access function shows up. The code is open for anyone to check on GitHub.
Pro configs
Crosshair, sens and viewmodel from 30 pros, ready to copy
From FalleN to ZywOo, with the source and check date for every player.
- Crosshair code to paste in the game, or the console commands.
- Sensitivity converter: the pro's sens at your mouse's DPI.
- Nothing is applied automatically. You look and copy if you want.
Everything included
Truly free, no limits at all
No paid version, no ads and no optimization quota.
Built-in benchmark
Average FPS, 1% low, 0.1% low and stutters, with a before/after chart and a ready-to-share image.
Before → now check
Shows the previous value, what was written and what is in Windows now. If an update undid something, you see it.
Cleanup
Temp files, crash reports and, if you want, shader caches. Shows how much it will free before deleting.
Mouse test
Measures your mouse's real polling rate and warns you if it is at 125 Hz.
Automatic updates
New versions arrive signed and install without losing your tweaks.
Uninstalls cleanly
When uninstalling, CSBoost offers to undo all tweaks before it goes.

People using it
Straight from the CS group
What players said after running CSBoost on their own PC.
Bro, mine was at 54 out of 100, lol. Now it's great: 100. I think it was running on the integrated GPU, even though I have an 8 GB RTX 5060.
It was already at 88, but now it's spot on. Awesome, man.
Just downloaded it and I'm already using it. This is going places, bro.
Just found it. You're a hero, thanks!
Man, just saw this. Pretty amazing!
Real comments on the launch post in a Brazilian CS2 Facebook group (translated from Portuguese). The score is CSBoost's dashboard score, from 0 to 100.
FAQ
Questions everyone asks
Can it get me banned (VAC)?
CSBoost was built around that rule. It does not open the game process, injects nothing and does not change CS2 files other than the autoexec.cfg you ask it to save. The tweaks are Windows settings, the same ones you would change by hand in Control Panel.
The code is open, so anyone can check what it does.
Why do Windows or antivirus show a warning?
The installer does not have a code signing certificate yet; it is on the way. A new, unsigned program that asks for admin rights often triggers SmartScreen and some antivirus heuristics.
Every version has its SHA256 published and a VirusTotal report with dozens of antivirus engines: see the report for the current version.
How much FPS will I gain?
It depends on what is wrong with your PC. On an already well-tuned PC, the gain is small. With the monitor at 60 Hz or a laptop on the integrated GPU, the difference is big.
That is why the benchmark exists: measure before, optimize and measure again on the same map.
How do I undo the tweaks?
In History, every tweak has a Revert button that restores the previous value. You can undo everything at once, and the uninstaller offers it too.
Does it work on laptops?
Yes. One tweak makes CS2 always use the dedicated graphics card, and tweaks that use more battery come with a warning.
Is it really free?
Yes. No ads, no limits and no paid version. If you want to support the project, there is Buy me a coffee.
Does it work for other games?
The Windows tweaks apply to any game. The specific parts, like pro configs, autoexec and the benchmark, are for CS2.
Run the PC Scan and see what is holding back your FPS
It takes a minute. If you don't like it, undo everything.
