High CPU usage while gaming makes your computer slow and laggy. Gaming uses lots of computer power, but too much CPU usage above 80% means your system has problems that need fixing right away.
CPU usage goes up during gaming because of background programs, old drivers, bad game settings, and not enough computer power. Big games like Cyberpunk 2077, Call of Duty, and Assassin’s Creed need lots of processing power, so fixing CPU problems is important for smooth gaming.
Lowering CPU usage makes games run 15-30% better and stops your computer from crashing during long gaming sessions. Players can use 12 easy ways to make their computer run better without buying new parts.
Understanding CPU Usage in Gaming
CPU usage shows how much of your computer’s brain is being used by programs and games running on your system. Gaming programs need lots of computer power to run physics, AI, and game actions.
Normal CPU Usage Levels
Good CPU usage during gaming should be between 50-70% for most new games. Usage above 80% means your computer is working too hard and needs help. How much CPU gets used depends on the game type, your computer specs, and other programs running.
Different game types use different amounts of CPU:
- Strategy games: 60-80% usage for smart computer players
- Shooter games: 40-60% usage for fast graphics
- Open world games: 70-90% usage for big game worlds
Signs of High CPU Usage
System lag and choppy gameplay means your CPU is working too hard during gaming. Common problems include low frame rates, crackling sound, slow controls, and frozen screens.
Warning signs include:
- Frame rates below 30 FPS all the time
- Computer temperature above 80°C
- Fans getting very loud
- Slow switching between programs
Close Background Programs
Closing extra programs reduces CPU usage by 20-40% while gaming. Many programs start automatically when you turn on your computer and use CPU power without you knowing.
Finding Programs That Use Too Much CPU
Task Manager shows which programs use the most CPU power on Windows computers. Press Ctrl+Shift+Esc to open Task Manager and sort programs by how much CPU they use.
Programs that use lots of CPU include:
- Web browsers with many tabs open
- Video editing programs like Adobe Premiere
- Streaming programs like OBS Studio
- Antivirus scans running all the time
Using Task Manager the Right Way
End programs you don’t need through Task Manager to free up computer power right away. Right-click on programs using too much CPU and click “End Task” for programs you don’t need.
Steps to fix CPU usage:
- Open Task Manager with Ctrl+Shift+Esc
- Click the “Processes” tab
- Click the CPU column to sort by usage
- End programs you don’t need that use lots of CPU
Update Graphics Drivers
Old graphics drivers make CPU usage go up by 25-35% because your main processor has to do graphics work. Getting new drivers helps your graphics card work better and use less CPU power.
AMD Driver Updates
AMD Radeon Software gives you new drivers automatically for better gaming. Download new drivers from AMD’s website or use the update button in Radeon Software.
New AMD drivers give you:
- Better support for new games

Adjust Game Settings
Lowering graphics settings reduces CPU usage by 15-25% while keeping games fun to play. Many visual effects need lots of CPU power and can be turned down without making games look bad.
Graphics Quality Options
Medium graphics settings give the best balance between how games look and CPU performance for most computers. Ultra settings often look only slightly better but use much more CPU power.
Good graphics changes include:
- Shadows: Medium instead of Ultra saves 10-15% CPU
- Anti-aliasing: Use FXAA instead of MSAA for speed
- Draw distance: Set to 75% of highest setting
- Texture quality: High instead of Ultra for balance
Screen Resolution
Lowering resolution from 4K to 1440p cuts CPU usage by 20-30% while keeping games looking sharp. Lower resolutions need less computer power to make frames and effects.
Resolution comparison:
- 4K (3840×2160): Highest CPU use, best looks
- 1440p (2560×1440): Good balance of speed and looks
- 1080p (1920×1080): Lower CPU use, good looks
- 900p (1600×900): Very low CPU use, okay looks
Turn Off Windows Game Mode
Windows Game Mode can make CPU usage go up by 10-15% on some computers even though it’s meant to help gaming. This feature changes how your computer uses power, sometimes making problems with game performance.
Turning Off Game Mode
Turn off Game Mode through Windows Settings to stop background programs from interfering. Go to Settings > Gaming > Game Mode and turn the feature off.
