💾 15 Hidden Windows Registry Tweaks for Maximum FPS and Zero Latency

The Advanced PC Optimization Guide for Competitive Gamers

Registry tweaks are one of the most effective ways to secretly boost your gaming performance, reduce input latency, and fix system-wide stutters. This guide details 15 advanced registry settings that actually work, ensuring your PC prioritizes your games above all else.

⚠️ Critical First Step: Create a System Restore Point

Before making any changes to the Windows Registry, you must create a System Restore Point. This allows you to completely revert all tweaks if you encounter any instability.

• 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., "Registry Tweaks Backup").

I understand. You want a straightforward, numbered summary that describes each of the 15 registry tweaks from the video, focusing on the action and purpose as described in the source material.

Here is the requested summary, presented as a numbered list of the individual tweaks:

Summary: 15 Hidden Registry Tweaks for FPS Boost and Zero Delay

The following list details the 15 registry tweaks and system optimizations described in the video, designed to maximize gaming performance and reduce input latency in Windows.

1. Windows 32 Priority Separation

   • Description: This tweak modifies a registry value to control how the CPU divides priority between foreground applications (your game) and background tasks, ensuring the game receives maximum attention.

   • Action: Set the registry value to 26 (Hexadecimal).

2. Decrease Mouse/Keyboard Data Q Size

   • Description: This involves modifying the size of the system's buffer (the data queue) that temporarily stores mouse movements and keystrokes before they are processed. Decreasing the size reduces the wait time, lowering input latency.

   • Action: The specific value is dependent on the type of CPU you have (low-end, mid-range, or high-end).

3. Disable Nagle's Algorithm

   • Description: Nagle's algorithm is a network protocol that bundles small outgoing data packets into a larger single packet to save bandwidth. Disabling it forces packets to be sent immediately, which drastically reduces network latency (ping).

   • Action: Create or set TcpAckFrequency to 1, TCPNoDelay to 1, and TcpDelAckTicks to 0 in your network interface's registry path.

4. Stop Internet Connectivity Checks (Enable Active Probing)

   • Description: This prevents Windows from automatically sending out probes (small network packets) to check and confirm internet connectivity in the background.

   • Action: Create or set EnableActiveProbing to 0.

5. Disable Network Throttling

   • Description: This tweak removes artificial limits or "throttling" that Windows places on network-related tasks, allowing for higher, unimpeded network performance.

   • Action: Set NetworkThrottlingIndex to FFFFFFFF (Hexadecimal).

6. System Responsiveness

   • Description: Similar to Tweak #1, this setting controls the amount of CPU resources reserved for non-gaming background tasks. Setting it to the lowest value ensures the game gets priority.

   • Action: Set the registry value to 10 (Decimal).

7. Disable Selective Suspend

   • Description: This is a power-saving feature that allows the system to put unused USB ports into a low-power state. Disabling it ensures constant power to all USB peripherals, fixing potential latency issues with mice and keyboards.

   • Action: Create or set DisableSelectiveSuspend to 1.

8. Disable Power Throttling

   • Description: This prevents the CPU from downscaling its frequency or performance to save energy. It is recommended only for systems that do not have overheating issues.

   • Action: Set PowerThrottling to 1. (If overheating is an issue, the video recommends setting it to 0).

9. Disable Timer Coalescing

   • Description: This power-saving feature groups multiple hardware interrupts and events into a single event, which reduces CPU usage but significantly increases latency. Disabling it is optimal for performance.

   • Action: Set CoalescingTimerInterval to 0.

10. Disable Event Processing

    • Description: A general optimization tweak intended to reduce overhead associated with processing various system events in the background.

    • Action: Create or set EventProcessing to 0.

11. Disable CPU Throttle States

    • Description: Prevents the CPU from entering low-power idle modes or downscaling its frequency, ensuring it maintains a high, consistent clock speed.

    • Action: Change a relevant power-related value called ValueMin to 0.

12. Disable Prefetch

    • Description: Prefetch is a service that attempts to predict which programs or tasks you will use next and preloads them into memory. Disabling it frees up memory and disk resources.

    • Action: Set EnablePrefetcher to 0.

13. Enable/Disable TSX (CPU Optimization)

    • Description: Transactional Synchronization Extensions is a CPU feature that helps improve multi-threaded performance. Its optimal setting depends on the CPU manufacturer.

    • Action: For Intel CPUs, set the value to 0 (enabled). For AMD CPUs, set the value to 1 (disabled).

14. Disable GPU Preemption

    • Description: This setting allows graphics tasks to run to completion without interruption from the scheduler, which reduces overhead and improves overall graphics performance consistency.

    • Action: Create or set DisablePreemption to 1.

15. Disable HDCP

    • Description: HDCP (High-bandwidth Digital Content Protection) is a security feature that encrypts video and audio content to prevent unauthorized copying. Disabling it removes a background load on the GPU.

    • Action: Set a specific registry value to 1 for NVIDIA users, or run a provided Command Prompt command for AMD users.
