Every frame your PC
was built to deliver.

The KRX Utility puts Windows tuning, hardware insight, and game-ready optimizations in one clean app — less background noise, smoother frames, faster response.

The essentials to clean up Windows and claw back frames on your own.

Restore point before every change
  • Live system dashboard & hardware scan
  • Core Windows gaming optimizations
  • Power plan configuration
  • Basic debloating
  • Real-time CPU, GPU and RAM utilisation with temperatures, clock speeds and a hardware health report covering processor, graphics, memory and OS build.

    Establishes a baseline so every change is measured against how your system actually behaves.

  • Game Mode, Hardware-Accelerated GPU Scheduling, Game DVR / background recording off and Xbox Game Bar control.

    Removes the most common sources of frame-time spikes with safe, reversible defaults.

  • Switch to a high-performance power profile with reduced CPU idle states during gameplay.

    Prevents the processor from down-clocking mid-match, keeping frame delivery consistent.

  • Uninstall unused applications and disable non-essential startup entries — every change can be toggled back on.

    Fewer resident processes free CPU time and memory for the game.

  • Windows temp, user temp, prefetch, recycle bin, recent items and thumbnail caches cleared in one pass.

    Recovers disk space and clears stale data that slows file access.

  • Ready-made competitive presets for popular titles.

    Low-input-lag settings without editing config files by hand.

  • Create a Windows restore point with one click before applying changes.

    A guaranteed rollback path if a setting does not suit your setup.

Every module unlocked, deeper tuning and lifetime updates to the app.

Lifetime updates & priority support
  • Everything in Starter
  • CPU scheduler & process priority tuning
  • Timer resolution & latency tuning
  • Interrupt affinity, MSI mode & core parking
  • Every free module included, in the same application — no reinstall required.

    Premium extends the free toolset rather than replacing it.

  • Win32PrioritySeparation quantum tuning, foreground boost, MMCSS (Multimedia Class Scheduler) game-task priorities and system responsiveness values.

    Gives the game thread priority access to CPU time, reducing scheduling delays that read as input lag.

  • High-resolution system timer configuration, dynamic tick and HPET-related settings, plus reduced DPC latency sources.

    Tighter timer resolution produces more consistent frame pacing and lower input-to-photon latency.

  • Message-Signaled Interrupts for GPU, NIC and USB controllers, interrupt affinity assignment and core-parking / C-state control.

    Keeps device interrupts off the cores your game uses and stops cores sleeping mid-frame.

  • TCP/IP stack tuning (Nagle's algorithm, auto-tuning, ACK frequency, RSS), NIC adapter properties (interrupt moderation, flow control, offloads, buffers), QoS policy and DNS optimisation.

    Reduces packet-processing delay and jitter for steadier ping and more consistent hit registration.

  • Standby list cleanup, memory compression and paging behaviour, superfetch / SysMain control and RAM cleaner.

    Prevents stutter caused by memory pressure during long sessions.

  • The complete performance, system and graphics tweak set, including windowed-game optimisations, power throttling off and network throttling off, with apply-all / revert-all.

    Tunes every layer of Windows rather than only the basics.

  • Grouped control of Defender, Windows Update, telemetry, account sync, sharing, Bluetooth discovery, remote access and device sensors — each with a clear explanation.

    Brings background processes down toward 60–70 for a quieter, more predictable system.

  • Logon items, scheduled tasks, diagnostic tracking and update services handled alongside application removal.

    Removes the hidden background activity standard cleaners leave behind.

  • Automated DDU-based clean reinstall with a stripped, debloated driver build, plus GPU tuning and chipset driver installation for AMD and Intel platforms.

    A clean driver stack removes overlays and telemetry that add render latency.

  • Fortnite, Black Ops 6/7, Counter-Strike 2, Apex Legends, Battlefield and more — configs backed up once and locked read-only so games cannot overwrite them.

    Competitive settings persist through game updates.

  • Hardware acceleration, notifications and telemetry disabled in Chrome, Edge, Brave, Opera, Firefox, Discord and Spotify; Discord CPU priority lowered.

    Background apps stop competing with the game for GPU and CPU resources.

  • USB power saving off, input queue sizes and polling-related settings for mouse and keyboard.

    More consistent input delivery from your peripherals to the game.

  • Shader caches (NVIDIA, AMD, DirectX), browser caches, crash dumps and device-level cleanup.

    Clears stale caches that cause hitching after driver or game updates.

  • Repairs for GTA V / FiveM, Rockstar Launcher, Xbox & Game Pass authentication, Valorant Vanguard, Epic Games, Call of Duty, Roblox and more.

    Resolves common launcher and anti-cheat errors without manual troubleshooting.

  • Reads live firmware values — PBO, Curve Optimizer, boost, C-states, memory profile, Infinity Fabric, Resizable BAR and virtualisation — on AM4, AM5 and Intel boards with AMI firmware.

    Shows exactly what your BIOS is running before any tuning decisions.

  • Advanced system options, benchmark tools and before / after reports.

    Verify every change with measurable results.

  • All future application updates and new modules, plus priority assistance in the KRX Discord.

    A single payment that keeps delivering new tweaks and fixes.
