10 Hidden Windows Tweaks for Maximum Gaming FPS and Zero Input Delay
Are you looking to squeeze every last drop of performance from your gaming rig? While major optimizations like driver updates and in-game settings are essential, true competitive advantage often lies in the hidden corners of your Windows operating system.
This guide breaks down ten lesser-known Windows tweaks that dramatically boost your FPS consistency and slash input latency, giving you the edge you need in any competitive title.
⚠️ Before You Start: Create a Restore Point
Before making any changes to your system registry or services, it is critical to create a system restore point. This ensures you can safely revert all modifications if you encounter any unexpected issues.
How to create a restore point: Search for "Create a restore point" in the Windows search bar, click Create, and name your backup (e.g., "Tweaks Backup").
The 10 Essential Hidden Windows Optimizations
| # | Optimization | Action | Rationale |
| 1. | Optimize SysMain (Superfetch) | Go to Services and find SysMain. If you are on Windows 10, set the startup type to Disabled. If you are on Windows 11, set it to Automatic (the service is more efficient on Win 11). | Disabling on Windows 10 prevents high disk and CPU usage caused by pre-loading frequently used apps. |
| 2. | Disable Timer Coalescing | In the Registry Editor (regedit), navigate to: HKLM\SYSTEM\CurrentControlSet\Control\Power. Create a new DWORD value called CoalescingTimerInterval and set its value to 0. | This feature saves power by grouping background tasks, but the resulting delays lead to inconsistent input lag and frame times. |
| 3. | Enable Write Caching | Go to Device Manager > Disk Drives, select your main drive, go to Policies, and check Enable write caching on the device. | This is a general performance booster. (Note: Should not be enabled if your location is prone to power outages, as it risks data loss.) |
| 4. | Disable Dynamic Tick | Run this command in Command Prompt (CMD): bcdedit /set disabledynamictick yes | Stops Windows from pausing timer updates, which causes inconsistent frame pacing and input delay. Recommended for stable performance unless you are on a thermally restricted laptop or low-end PC. |
| 5. | Enable Task Offloading | Run this command in Command Prompt (CMD): netsh int ip set global taskoffload=enabled | Offloads network-related tasks (like packet segmentation) from your CPU to your network adapter, significantly lowering CPU utilization. |
| 6. | Disable NDU (Network Data Usage) | In the Registry Editor (regedit), navigate to: HKLM\SYSTEM\CurrentControlSet\Services\Ndu. Find the NDU service and set its Start value to 4. | Saves memory and CPU resources by stopping the background network data tracker. |
| 7. | Disable DiagTrack (Diagnostic Tracking) | Go to Services, find Connected User Experiences and Telemetry, and set the Startup type to Disabled. | Stops the collection of diagnostic data that consumes system resources and bandwidth. (Set to Manual if you frequently use diagnostic tools.) |
| 8. | Memory Compression | Run the appropriate command in PowerShell: – If you have > 16 GB of RAM: – If you have < 16 GB of RAM: | On systems with high RAM, the CPU cost of compressing pages outweighs the memory savings. Disabling it provides better performance. |
| 9. | Disable Fast Startup | Go to Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do, and uncheck Turn on fast startup (recommended). | Ensures a complete restart of your PC and drivers every time, which is essential for stability and applying deep system changes. |
| 10. | Disable Connected Standby | In the Registry Editor (regedit), navigate to: HKLM\SYSTEM\CurrentControlSet\Control\Power. Create a new DWORD value called CsEnabled and set its value to 0. | Prevents the CPU from entering low-power "standby" states, maintaining consistent performance during gameplay. |
Final Step
After successfully applying all ten tweaks, you must restart your PC for the registry and service changes to take effect. Enjoy the boost to your FPS and the new level of responsiveness!
