Boost FPS in Real-time

PC Game Booster is an effective solution to boost in-game frames per second (FPS). Unlike other game boosters, it not only suspends unnecessary features to enhance performance but also works in the background to manage running processes to enable games and applications you use to receive priority access to the CPU, GPU, and RAM, while preventing non-essential components from consuming available resources. All of this occurs without compromising system stability, resulting in smoother gameplay, higher frame rates, and no FPS drops.

Reduce Overhead

PC Game Booster makes it easy to detect and suspend processes, Windows services, and scheduled tasks from both system and third-party apps — helping improve performance and reduce overhead. Normally, users would need expert knowledge to identify which processes and services belong to a specific app and whether it is safe to suspend during gameplay. However, PC Game Booster eliminates this complexity by using a smart algorithm that detects and suspends those components in one click, and automatically restores them after you finish gaming.

PC Game Booster makes it very easy to detect and suspend processes, Windows services, and scheduled tasks of system and third-party apps to help improve performance and reduce overhead.
PC Game Booster disables Windows Update, suspends Windows Defender scans, disables CPU core parking, and applies several Windows tweaks to help optimize your PC for gaming and streamline your gaming experience.

Streamline Your Gaming Experience

PC Game Booster streamlines your gaming experience by disabling non-essential Windows features such as Windows Update and Windows Defender scans, which can cause stuttering, FPS drops, and lag during gameplay. Beyond disabling these features, PC Game Booster also applies several system tweaks to optimize your PC for gaming — including the activation of a dedicated game power plan, disabling Windows visual effects, and fine-tuning other performance-critical settings. With just one click, it temporarily disables all resource-intensive functions, then automatically restores everything after gaming.

FPS Booster FAQs

Frequently asked questions about how PC Game Booster can optimize your PC's performance and the features it offers to increase in-game FPS.

Does PC Game Booster really boost game FPS?

Yes, PC Game Booster delivers measurable improvements in frame rates and stability, as well as enhanced system and application performance and responsiveness. However, results may vary based on your hardware and current system settings.

The software helps you take full advantage of your existing hardware, allowing you to get the best possible gaming performance without the need for immediate hardware upgrades.

What is Live Optimization feature in PC Game Booster?

Live Optimization is a dynamic feature in PC Game Booster — a powerful FPS booster and app optimizer — that enhances your system's performance and responsiveness while gaming or using resource-intensive applications. It works intelligently in real time by managing process priorities and memory usage, helping boost FPS and optimize Windows for smoother gameplay without manual intervention.

How does Live Optimization boost FPS in games?

Live Optimization uses three core mechanisms to boost FPS and enhance gaming performance:

  • Priority Boosting: Automatically detects active game processes and elevates their processing priority, ensuring they receive maximum access to CPU and system resources.
  • Background Throttling: Identifies unnecessary background processes and restricts their resource access, preventing interference with foreground gaming performance. This helps optimize Windows by stopping non-essential tasks from consuming valuable resources.
  • Memory Reclamation: Frees up system memory by trimming usage from inactive or low-priority processes, giving your game access to more available RAM for a consistent FPS boost.
How do I enable Live Optimization to boost FPS?

Live Optimization is part of Game Mode. To enable this powerful game booster feature:

  1. Open PC Game Booster.
  2. Click the Turn on Game Mode button.
  3. In the Game Mode configuration window, check the option labeled Boost games performance in real-time.

When Game Mode is activated, PC Game Booster automatically enables Live Optimization and displays a confirmation notification in the lower-right corner of your screen.

Will I receive notifications when Live Optimization takes action?

Yes. When Live Optimization boosts or throttles a process, a notification appears in the lower-right corner of your screen, informing you which process was optimized.

You can customize these notifications by going to Settings Notifications Live Optimization Notifications, so you stay informed about how PC Game Booster helps optimize Windows during gameplay.

What is the Live Optimization Log?

The Live Optimization Log provides a detailed record of all real-time optimization actions performed by PC Game Booster. It helps you monitor exactly how the game booster adjusts process priorities to boost FPS and enhance performance.

To open the Live Optimization Log:

  1. Right-click the PC Game Booster icon in the system tray
  2. Select Live Optimization Log.
How do I exclude a process from Live Optimization?

You can exclude a process from Live Optimization in two ways to fine-tune how PC Game Booster helps optimize your PC:

  • Live Optimization Log: Right-click any log entry and select Exclude Process
  • PC Game Booster Settings: Settings > Live Optimization > Exclude processes and apps from Live Optimization and manage your exclusion list manually

Once excluded, Live Optimization will no longer boost, throttle, or reclaim memory from that process.

What is System Optimizer?

System Optimizer is a powerful feature in PC Game Booster that provides a suite of tweaks designed to enhance system responsiveness, reduce background interruptions, and improve internet connectivity — all of which help boost FPS and optimize Windows for gaming. These tweaks are especially useful for gamers seeking smoother gameplay and faster system behavior.

System Optimizer organizes tweaks into four intuitive categories:

  • System — Core OS behaviors like memory cache, boot optimization, and shutdown speed.
  • Internet — Network settings to reduce latency and improve connection stability.
  • Applications — Background services and app behaviors that may interfere with gaming.
  • Visual Effects — UI enhancements that can be disabled to free up system resources.

Each tweak includes a description of the default Windows behavior and a recommendation explaining how PC Game Booster modifies it for better performance.
