ACE-YES Process Optimizer

A lightweight, high-performance process optimizer designed to tame resource-heavy background services like ACE/SGuard.

Highlights

  • 🚀 Ultralight & Invisible
    • Tiny Footprint: Single standalone executable with no external dependencies.
    • Zero Impact: Consumes only ~2MB RAM with negligible CPU usage. No impact on gaming FPS.
  • 💾 Disk Saver
    • Reduce Wear: Intelligently detects and suppresses aggressive disk scanning behavior, significantly extending SSD lifespan and silencing HDD noise.
    • IO Priority Lock: Forces target processes to the lowest I/O priority to prevent background scans from stuttering your foreground apps.
  • 🛡️ Safe & Open Source
    • Transparent: 100% open-source code. No hidden backdoors.
    • Ban-Safe: No injection or memory modification involved. Uses only standard Windows scheduling APIs to manage resources, ensuring compliance with anti-cheat rules.

Introduction

ACE-YES is a Windows utility designed to automatically detect and restrict resource-heavy background processes (specifically configured for SGuard64.exe and SGuardSvc64.exe). It sits quietly in the system tray and applies CPU affinity, priority reduction, and Smart Cooling (intelligent suspension) to target processes, ensuring your system remains responsive and cool.

Key Features

  • Smart Cooling:
    • Auto-Suspend: Automatically suspends the process for 50 seconds if it exceeds 5% CPU or 1MB/s Disk I/O.
    • Safety Window: Automatically resumes the process for a 5-second protection window to ensure heartbeat packets are sent, preventing connection timeouts.
  • Resource Limiting:
    • CPU Affinity: Binds the process to the last logical core only.
    • Priority: Sets CPU, I/O, and Memory priority to Very Low / Idle.
    • EcoQoS: Enforces Windows 11 Efficiency Mode (EcoQoS) for maximum power saving.
  • System Tray:
    • Right-click to toggle "Smart Cooling" on/off.
    • Quick access to logs and auto-start configuration.
  • Dual Architecture: Available for both x64 (Recommended) and x86 (32-bit) systems.

Requirements

  • Windows 10 or Windows 11.
  • Run as Administrator (Required to manage system-level services).

Usage

  1. Download the latest release from the Releases Page.
  2. Run ACE-YES.exe as Administrator.
  3. The app will minimize to the system tray (Fire icon 🔥).
  4. Done! It will automatically detect and optimize SGuard immediately upon startup.

Build Instructions

Prerequisites

  • Visual Studio 2022 ("Desktop development with C++").

Command Line Build

# Build x64 (Recommended)
msbuild ACE-YES.vcxproj /p:Configuration=Release /p:Platform=x64

# Build x86 (32-bit Compatibility)
msbuild ACE-YES.vcxproj /p:Configuration=Release /p:Platform=x86

Configuration

To monitor different processes, simply modify the TARGET_PROCESSES vector in ACE-YES.cpp and recompile:

std::vector<std::wstring> TARGET_PROCESSES = { L"SGuard64.exe", L"SGuardSvc64.exe" };
