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 — PULSE runs with administrator rights.
3. Open the dashboard and run a one-click optimize to apply a safe baseline.

Everything is reversible. Get the installer on the download page.

Windows 10 1809+ or Windows 11, 64-bit. Administrator rights are required for system tweaks (UAC prompts on first run only). Less than 50 MB RAM idle.

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.

We're obtaining an EV code-signing certificate; until then installers are unsigned and may trigger SmartScreen. You can verify the download yourself against the SHA-256 hash published on the download page. 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.

Persistent tweaks live in Windows itself — once applied, they stay applied whether PULSE is open or not.

Live monitoring, Live Tune, per-game auto-apply profiles, and the thermal protection behind GPU overclocking do need the app running. PULSE idles light — under 50 MB of RAM — so leaving it in the tray costs almost nothing.

Four layers: GPU overclocking within hardware-safe limits, CPU priority and core affinity so the game gets dedicated cores, 84+ Windows registry and service tweaks that cut DPC latency and frametime spikes, and per-game NVIDIA driver profiles.

Typical gains are 15–45% more FPS on many CPU-bound games — results vary by game and hardware, and GPU-bound titles see less.

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.
• An emergency thermal cutoff (tier-dependent, up to ~90 °C) 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.

NVIDIA GTX 900 series and newer (NvAPI). AMD RX 400 series and newer, including RDNA 4 (ADL + ADLX). Intel Arc — detected and monitored only (no public OC API).

FPS and frametime readings require RivaTuner Statistics Server (RTSS) — not bundled, installed separately. The full breakdown lives on the compatibility page.

Start with the basics: current GPU drivers, games on an SSD, and nothing running that you don't need. The remaining wins live in the system layer — power plan, background services, timer resolution, CPU scheduling, and GPU headroom.

PULSE automates that system layer. One-click optimize applies a safe baseline, every change is snapshotted first, and on many CPU-bound games the result is 15–45% more FPS. GPU-bound titles see less — no optimizer changes what your graphics card can draw.

It depends on your bottleneck. When background load, a conservative power plan, or scheduling jitter is holding a game back, removing that overhead genuinely helps — which is why gains concentrate on CPU-bound games, typically 15–45% in many of them.

When the GPU is the limit, system tweaks have much less to give. PULSE is built around that honesty: it measures with real sensors, shows you what changed, and never invents a number.

Input lag builds up across layers: render queues, timer granularity, background load, and power-saving states that slow the CPU mid-input. No single switch removes it all.

PULSE ships a dedicated input-delay tweak category plus per-game CPU priority and core affinity, so your game's threads aren't pre-empted by background tasks. Pair that with in-game settings — raw input on, and a frame cap just under your monitor's refresh rate.

Not below the floor — your distance to the server and your ISP's routing decide the minimum, and no app changes that.

What software can fix is everything above that floor: QoS stops a background download from spiking your latency mid-match, per-app firewall rules silence chatty programs, and a DNS benchmark speeds up lookups. PULSE does all three and shows real ping to game servers before you queue.

No. 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.

PULSE only changes Windows settings and driver parameters. It never injects into games, modifies game files, or interacts with anti-cheat. Every change is recorded to a JSON snapshot first — one click to revert any of it.

Yes. Every overclock value is clamped to the limits reported by NvAPI (NVIDIA) or ADL/ADLX (AMD), so you can't push beyond what the driver permits.

PULSE enforces an emergency thermal cutoff (tier-dependent, up to ~90 °C), requires a 20% minimum fan speed, and rolls back clocks immediately if a power-limit write fails. All offsets are volatile — a reboot or driver crash resets them.

Three-tier presets (Safe / Balanced / Max) for non-experts; advanced mode for tuners.

The category has a deserved trust problem — fake boosters and registry cleaners that do more harm than good. The test is simple: does the tool say exactly what it changes, can it undo everything, and does it stay out of your games?

PULSE is built to pass that test. Every change is recorded to a JSON snapshot before it is written, one click reverts it, there is no kernel driver, and every installer publishes a SHA-256 hash you can verify before running it.

You can download and use the free tier without an account. Anonymous product analytics — no name, no email, no hardware fingerprint, just a random resettable install ID — are on by default and can be turned off in Settings → Privacy. Crash reports are off unless you opt in.

Snapshots, logs, and optimization backups stay on your PC. The full detail is in the privacy policy.

No — PULSE is a single small Rust binary, not an Electron app. It idles under 50 MB of RAM and polls sensors on a fixed cadence, so it stays out of your game's way. If you ever want it gone, the uninstaller reverses the system changes it made as it removes the app.

Yes. The free tier covers real-time monitoring, FPS and frametime via RTSS, system info, and session history — free forever, no account required to download. Pro unlocks the full optimization suite.

See the full Free vs Pro comparison on the pricing page.

Pro starts with a 7-day free trial. There's no charge for 7 days, and you can cancel anytime. After the trial, your subscription renews at the price you signed up at.

Early Supporter is a permanent discount available only during the first 3 months after launch. You pay $19.99/year instead of the standard $29.99 — and your price is locked in for as long as your subscription stays active.
