SIX AREAS OF CONTROLOPEN TO EXPLORE
System & maintenanceThe Windows settings behind your everyday setup.

What’s insidePower plans, cleanup, maintenance, and update settings.

Choose changes around how you use your PC, from daily work to dedicated gaming sessions.

Latency & inputExplore how your system handles input and timing.

What’s insideInput settings, system timers, and timer resolution.

Timing changes are system-dependent. Measure your own sessions before deciding what to keep.

Hardware & powerFine-tune the settings around your components.

What’s insideCPU scheduling, GPU settings, memory, storage, and power behavior.

Check hardware compatibility and the trade-offs between responsiveness, energy use, and thermals.

Debloat & privacyDecide what runs in the background.

What’s insideWindows services, background apps, privacy settings, and interface options.

Review what each component does before disabling it; other apps or Windows features may rely on it.

Boot & startupTake a closer look at how Windows starts.

What’s insideStartup behavior, kernel settings, and hypervisor options.

Advanced boot changes can affect security and compatibility. Read the individual warnings first.

Network & connectivityUnderstand the settings behind your connection.

What’s insideDNS, TCP/IP, network adapters, and packet handling.

The right settings depend on your adapter and network. Compare results rather than assuming lower ping.

A library to choose from. Apply only what fits your system.

SELECTED TWEAKS

What you can adjust.

Concrete settings, documented effects, and the requirements to check before applying them.

Swipe or scroll to explore

TIMER RESOLUTION

Set Timer Resolution

Adjusts the Windows timer interval for latency-sensitive apps and games.

Documented risk
Low
Administrator access
Required
Restart
Not required

A finer interval can increase CPU wake-ups and power use. Compare input response and frame pacing on your system.

POWER PLANS

Nova Tweaks Ultimate Powerplan

Activates Nova’s custom power plan, prioritizing processor performance over energy savings.

Documented risk
Low
Administrator access
Required
Restart
Not required

For demanding desktop workloads. Higher power draw and temperatures are possible.

NVIDIA PROFILE PRESETS

NVIDIA Profile Presets

Applies a global NVIDIA driver preset: Competitive, Balanced, Quality, or Restore Defaults.

Documented risk
Low
Administrator access
Required
Restart
Not required

Requires compatible NVIDIA hardware and drivers. Restore Defaults resets the global profile to driver defaults.

MEMORY

Clear Standby List

Clears cached memory pages to help troubleshoot stutters after long gaming sessions or heavy multitasking.

Documented risk
Low
Administrator access
Required
Restart
Not required

Windows rebuilds the cache automatically. Frequent clearing can cause temporary slowdowns; it does not permanently increase FPS.

TCP/IP

Set TCP Auto-Tuning Level

Sets Windows TCP receive-window auto-tuning to Normal, Restricted, or Disabled.

Documented risk
Medium
Administrator access
Required
Restart
Not required

An advanced network setting. Normal is the recommended selection; Restore returns the level to Normal.

YOUR FIRST TUNING PASS

Back up first.
Then change one thing at a time.

  1. 01

    Back up

    Create a Nova backup and a Windows restore point.

  2. 02

    Choose deliberately

    Read the effect, risk, and requirements of each tweak.

  3. 03

    Compare

    Check your baseline, frametimes, and everyday use.

01 / THE TOOLKIT

Tune Windows.
Test the result.

A tweak is only useful if it helps on your PC. Check the settings, then test before and after under the same conditions.

01Overview

Check temperatures and load.

Check how hard your PC is working before changing a setting. See CPU and GPU readings alongside memory usage and drive stats.

  • CPU and GPU temperatures
  • Clock speeds and memory usage
02Tweaks

Read the tweak before applying it.

See what each setting changes and whether it is already applied. Check the risks and requirements, then change one setting at a time.

  • 140+ documented tweaks
  • Effects, risks, and requirements
03Automation

Run tweaks when a game starts.

Create a rule to apply a tweak when your game starts. Add another to reset it when the game closes. You choose the condition and action.

  • Game-start and game-close triggers
  • CPU temperature alerts
04Performance

Check FPS and frametimes.

Run the same test before and after a change. Compare average FPS, 1% lows, and frametimes to see whether it helped on your PC.

  • Average FPS and 1% lows
  • Frametimes for checking frame pacing
BEFORE YOU APPLY A CHANGE

Backup &
Restore.

Keep Nova configuration backups and Windows restore points in one history.

Nova configuration backups
Save Nova settings and supported tweak states before a tuning pass.
Automatic backups
Schedule configuration backups and check their date, type, and status in the history.
Review before restoring
Inspect what a backup includes, then restore supported settings or use a Windows restore point.

Nova backups cover supported configuration changes. They do not replace a full file or system backup, and not every change can be restored.

GOOD TO KNOW

Before You Tune.

Is it really free?

Yes. Nova Tweaks is open source under GNU GPLv3. No subscriptions, paid tiers, or accounts.

Which Windows versions are supported?

Windows 10 and Windows 11 on x64 systems. Check the GitHub release notes for current requirements.

What should I check before installing?

Use the direct Windows download or the Microsoft Store badge. Compare the installer's SHA-256 hash with the value in checksums.txt, using PowerShell's Get-FileHash command. A matching hash confirms that the file matches the published download; it does not establish that the software is safe. Read the release notes and back up before applying changes.

Why might Edge or Windows show an installation warning?

Version 1.1.2 is digitally signed by Open Source Developer Elia Willi Klemenz. Windows has verified the installer's publisher signature. Signing identifies the publisher and lets Windows check that the signed file has not been altered. Edge may still show “isn't commonly downloaded”: SmartScreen also checks download and publisher reputation, which is separate from a valid signature. This particular message does not mean a virus was found. You can check the signature under Properties → Digital Signatures and compare the file with our published SHA-256 checksum. Our source code and release notes are public. If a warning names a specific threat or the signature is invalid, leave the file unopened and share the exact message with us. Microsoft explains download reputation here.

Earlier release: these screenshots show version 1.0.2, before code signing.

Who maintains Nova Tweaks?

Nova Tweaks is maintained by Elia (NovaTweaksDev). The source code, release history, and issue tracker are public on GitHub. You can ask a question or report a problem there.

Can I undo my changes?

Create a Nova configuration backup and a Windows restore point before changing settings. You can restore supported changes, but not every tweak can be undone through Nova. Keep a separate backup of important files.

Will it increase my FPS?

Results depend on your hardware and settings. Compare baseline sessions and frametimes to see what helps your system.

Do I need to apply every tweak?

No. The 140+ documented tweaks are a toolkit to choose from. Review the effect, risk, compatibility, and current state, then apply only the changes that suit your setup.

Will I need administrator access or a restart?

Some changes require administrator access or a restart. Nova documents these requirements per tweak and requests elevation when a supported operation needs it.
