Razer Game Booster
Razer Game Booster (now part of Razer Cortex) was a system optimization tool that temporarily shut down unnecessary background processes and services when launching games, freeing up RAM and CPU resources for better gaming performance.
What it does
When you launch a game through the booster, it suspends non-essential Windows services, background applications, and scheduled tasks. This frees system resources for the game. When you exit the game, everything is restored to normal. A game launcher organizes your installed games with cover art and launch buttons.
The tool evolved into Razer Cortex, which adds FPS monitoring, screenshot capture, and system cleaning. A defragmentation feature optimized game file placement on hard drives (less relevant with SSDs).
Advantages
- One-click resource optimization for gaming
- Automatic restoration after gaming session
- Game library organizer
- Free to use
Drawbacks
- Minimal real impact on modern hardware with abundant RAM
- Windows Game Mode does the same thing natively
- Can cause issues if it suspends needed services
- Modern PCs rarely benefit from process suspension
Who it is for
Game Booster was most useful on older PCs with limited RAM where freeing 200-500 MB made a noticeable difference. Modern systems with 16-32 GB RAM see negligible improvement from killing background processes. Windows 10/11 Game Mode provides similar optimization natively without additional software.
