Everything else can wait.
DecreaseLag puts your game ahead of every other process and every other packet on your PC while you play. It never reads, writes, or injects into the game. Close it and every setting goes back.

Any game on Windows. It tunes your system and your connection, not the game, so it is not tied to a title.

Four changes while you play. Every setting back when you close it.
Each one is a change you could make by hand in Windows. DecreaseLag makes them together when you press Boost, and undoes them when you quit.
-
Network
Your game's packets go first
While you play, DecreaseLag marks your game's traffic as the priority on your PC's outbound queue. A download, a cloud sync or a stream on the same machine waits behind it instead of in front of it. Fewer queued packets means fewer spikes when it counts.
Outbound queue on your PC. Flip Boost above to see the order change. On closeThe priority rule is removed.
-
CPU and GPU
Windows feeds your game first
It raises your game's CPU and GPU process priority so the scheduler hands it resources ahead of everything else you have open. Smoother frames and fewer stutters in the middle of a fight.
On closePriority returns to normal.
-
Disk and memory
A clean slate before you drop in
It clears temp files and frees memory before you play, so nothing left over from earlier is sitting on resources in the middle of a match.
On closeNothing to restore. Temp files are junk, and freed memory is simply free.
-
Power
High performance while you play
It switches Windows to the high-performance power plan so your hardware is not asked to save energy mid-fight, then puts your usual plan back.
On closeYour previous power plan is restored.
-
Puts it back
One close undoes it
Every setting it changed is recorded and restored the moment you close the app. Want out early? Press Restore inside the app and it rolls back while it is still open. Nothing keeps running in the background.
-
Signed
A normal installer, nothing to paste
DecreaseLag ships as a code-signed Windows installer. No commands, no scripts, no unsigned downloads. It touches only your own Windows and network settings, which is why it stays clear of anti-cheat.
Install to in-game in under a minute.

The same simulated signal as the top of the page, with the frame-time channel added. Boost on: the ping line drops and tightens, the frame-time line flattens, the counters climb. Boost off: it all comes back, which is exactly what happens when you close the app.

Anti-cheat
There is nothing for anti-cheat to flag
DecreaseLag never reads, writes, or injects into your game. It adjusts your own Windows and network settings, the same things you could change by hand, so it is invisible to anti-cheat in the only way that matters: it is not in the game. It ships as a code-signed installer, and every setting it changes is rolled back on exit or the moment you press Restore.
Tweak by tweak, or one press.
These creators walk you through tuning Windows for FPS and ping by hand. DecreaseLag makes the same system-side changes in one press, then undoes them when you are done. Watch what is happening under the hood.

Straight answers.
What every careful player asks before installing anything.
Is DecreaseLag a cheat or hack?
No. DecreaseLag never touches your game. There is no injection, no file edit, no memory reading. It only changes your own Windows and network settings, the same ones you could change by hand in Windows. That is why it stays clear of anti-cheat.
Will I get banned for using it?
No. DecreaseLag never interacts with the game process or with anti-cheat, so there is nothing for anti-cheat to detect. It is the same category of change as switching Windows to the High performance plan or setting a process priority in Task Manager yourself.
Is it safe for my PC?
Yes. It makes standard, documented Windows changes, records each one, and restores them when you close it. The temp files it clears are junk and stay cleared; every setting goes back.
How do I undo the changes?
Close DecreaseLag and every setting it changed goes back automatically. You can also press Restore inside the app at any time while it is open.
Does it actually work?
It does the same four things performance creators walk you through by hand: prioritize game traffic, raise the game's priority, clear temp files and memory, and switch to the high-performance plan, all at once. How much you gain depends on your hardware, your connection, and the game. The network change matters most when something else on your PC is using your connection while you play.
Which games does it work with?
Any game on Windows: Roblox, Valorant, Fortnite, CS2, Apex Legends, Warzone, League of Legends, Overwatch 2, Rainbow Six Siege, Marvel Rivals and the rest. It tunes your system and connection, not the game, so it is not tied to a title.
Does it run in the background or slow my PC?
No. It only works while it is open and cleans up after itself when you close it. No background service is left running, there are no ads, and it is built to stay light.
Why is it free?
Because your gear should not decide who wins. There are no paywalls, no locked features, and no pro upsell.
Do I have to paste any commands?
Never. It is a normal, code-signed installer. Download, install, press Boost. No terminal, no scripts, no copying code from a video description.
Close it and every setting goes back.
Download DecreaseLag, press Boost, play. Quit whenever you like; it puts your settings back on the way out.
