Guides & help.

1. Download PULSE and run the installer.
2. System tweaks and overclocking change protected settings, so Windows will ask you to confirm a UAC prompt and PULSE runs with administrator rights.
3. Open the dashboard and run a one-click optimize to apply a safe baseline.

Everything is reversible. Every change is recorded before it is made, so you can undo any of it later.

GPU overclocking is a Pro feature. Pick one of three tier presets — Safe, Balanced, or Max — or open advanced mode to set your own clock and memory offsets.

• Every offset is clamped to what your hardware reports through NvAPI, ADL, or ADLX — PULSE will not push past your card's own limits.
• A 90 °C emergency cutoff backs the offsets out automatically if the GPU gets too hot.
• Offsets are volatile — they reset on reboot, so a bad setting never sticks.

Overclocking supported on NVIDIA GTX 900 series and newer, and AMD RX 400 series and newer including RDNA 4. Intel Arc is supported for monitoring.

PULSE ships 84+ tweaks grouped into categories. Each one toggles independently — turn on only what you want.

• Before any change, PULSE saves a JSON snapshot of the affected setting.
• Toggle a tweak off, or undo it in one click, and the original value is restored from that snapshot.

The Network section gives you a few tools for lower, steadier latency:

• Per-app firewall rules to control which programs reach the network.
• QoS to give game traffic priority over background downloads.
• A DNS benchmark to find the fastest resolver for your connection.
• Game-server ping so you can compare latency before you queue.

PULSE operates outside your games. It does not load a kernel driver and it never injects into or reads game process memory.

Because it stays out of the game itself, PULSE is compatible with the major anti-cheat systems — EAC, BattlEye, Vanguard, and VAC.

Windows Defender uses heuristics that often flag unsigned optimizers simply because they change system settings. The warning is about the missing signature, not about anything PULSE actually does.

You can verify the download yourself against the published SHA-256 hash. We also submit each release to Microsoft and the major antivirus vendors so the warning clears over time.

Use the bundled uninstaller — it reverses the system changes PULSE made, by category, as it removes the app.

You can also remove PULSE from Windows Apps & Features, which runs the same uninstaller.
