v1.0.0 — Official Public Release

v1.0.0 — Official Public Release

After 8 months of active development, FpsTweak has been rebuilt from scratch from an early C# foundation into an ultra-lean Tauri + Rust native application. Built specifically for competitive gamers, v1.0.0 eliminates Windows input latency, stabilizes 1% frametime lows, and introduces one-click pro esports configs with zero background resource drain.

Architecture & Core Engine

  • Rust & Tauri Core: Entire system engine completely rewritten in Rust for sub-20MB RAM usage, near-instant launch times, and 0% background CPU contention while gaming.

  • Passive Silent Auto-Updater: Frictionless, Discord-style background update downloads verified by cryptographic Ed25519 signatures, featuring atomic engine locking to prevent updating during active tweak applications.

  • One-Time UAC & Background Tray Launch: Seamless background startup with dedicated Task Scheduler elevation, running minimized to the system tray without recurring UAC popups or console flashes.

Tweak Engine & Failsafe Rollbacks

  • 150+ Precision System Tweaks: Modular Windows optimizations spanning registry latencies, timer resolution, DWM scheduling, CPU unparking, MSI-mode interrupts, and network QoS prioritization.

  • Automatic System Restore & Snapshots: Automated Windows restore point creation combined with local SQLite-backed original state snapshots before any value is modified.

  • Atomic Rollback & Safety Fallbacks: One-click rollback restores original system values instantly. Protected system keys and kernel driver states are gracefully handled without aborting overall optimization passes.

  • Anti-Cheat Safe by Design: Strips bloatware and unnecessary telemetry services with zero game binary modification, DLL injection, or anti-cheat flags across Vanguard, EAC, and BattlEye.

Esports Pro Settings & Game Profiles

  • One-Click Pro Player Sync: Directly inspect and apply verified mouse sensitivities, launch options, video settings, and configs used by tier-1 pros in Counter-Strike 2, Valorant, and Fortnite.

  • Dynamic Crosshair Simulation: Pixel-calibrated interactive canvas crosshair renderer modeling exact in-game sizes, gaps, alphas, and outlines across competitive resolutions.

  • “My Settings” Snapshot: Back up and restore your personal config snapshots locally, enabling instant switching between custom setups and pro configurations.

  • 50+ Game Presets: Tailored optimal and maximum performance video presets for popular competitive and AAA titles.

System Diagnostics & Maintenance

  • Smart RAM & Disk Cleaner: Automated working-set memory flushing and disk cache cleanup engineered to prevent micro-stutters and freeze frame spikes without background polling.

  • Live System Metrics: Real-time hardware temperature, CPU/GPU clock tracking, and an weighted PC optimization progress metric.

  • Full Bilingual Support: Native English and Turkish localization across all dashboard views, system presets, and individual tweak descriptions.
