What are the essential Windows 11 settings and toggles to tweak for maximum gaming FPS and lowest latency?

Windows 11 Gaming: 3 novità che eliminano i lag e aumentano gli FPS - Cdkeyit.it

1. Graphics & Display Settings

  • Game Mode: Go to Settings > Gaming > Game Mode and toggle On. This allocates CPU/GPU resources directly to the foreground game while suppressing background Windows updates and non-essential tasks.

  • Hardware-Accelerated GPU Scheduling (HAGS): Navigate to Settings > System > Display > Graphics > Change default graphics settings and turn On. HAGS offloads frame scheduling tasks from the CPU to a dedicated processor on the GPU, lowering input latency and enabling frame generation technologies (DLSS 3 / FSR 3).

  • Optimizations for Windowed Games: In the same Default graphics settings menu, toggle On. This upgrades legacy DirectX 10/11 windowed games to the modern Flip Model presentation, delivering the low latency and Variable Refresh Rate (VRR) support of Exclusive Fullscreen mode while remaining in borderless windowed mode.

  • Refresh Rate & System VRR: Under Settings > System > Display > Advanced display, ensure Choose a refresh rate is set to your monitor’s maximum supported Hz (e.g., 144Hz, 240Hz). If visible, enable the Variable Refresh Rate toggle to prevent screen tearing on non-G-Sync/FreeSync native displays.

2. Security Trade-Offs for Maximum CPU Performance

  • Core Isolation / Memory Integrity: Go to Settings > Privacy & security > Windows Security > Device security > Core isolation details and turn Memory Integrity to Off.

    • Impact: Disabling Virtualization-based Security (VBS) reclaims up to 3–10% FPS in CPU-bound competitive games (such as CS2, VALORANT, or Apex Legends). Note: This reduces protection against high-level kernel malware.

  • Virtual Machine Platform: Search for "Turn Windows features on or off" in the Start Menu and uncheck Virtual Machine Platform and Hyper-V if you do not run WSL or local VMs. Reboot to reclaim reserved CPU cycles.

3. Power & CPU Frequency Management

  • Power Mode: Go to Settings > System > Power and set Power mode to Best Performance. This prevents aggressive CPU downclocking during game loading transitions.

  • Ultimate Performance Plan: Open Terminal/Command Prompt as Administrator and run the following command to unlock the hidden power profile:

    DOS

    powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

    Then open Control Panel > Hardware and Sound > Power Options and select Ultimate Performance. This completely disables CPU core parking and latency-inducing power-saving states.

4. Overhead & Background Task Reduction

  • Disable Background Game DVR: Go to Settings > Gaming > Captures and toggle Record what happened to Off. Background screen recording constantly writes to temporary storage and consumes CPU threads. Use GPU-level overlays (NVIDIA ShadowPlay / AMD ReLive) instead if clips are needed.

  • Disable Startup Bloatware: Open Task Manager (Ctrl + Shift + Esc) > Startup apps and disable non-essential apps (e.g., OneDrive, RGB lighting control suites, browser updaters, secondary game launchers).

  • Nagle’s Algorithm / Network Latency (Optional): Ensure you are connected via Ethernet rather than Wi-Fi, and disable "Metered Connection" in Settings > Network & internet > Wi-Fi/Ethernet to allow steady packet flow.

Windows 7 Keyboard Shortcuts.

Keyboard shortcuts are combinations of two or more keys that, when pressed, can be used to perform a task that would typically require a mouse or other pointing device. Keyboard shortcuts can make it easier to interact with your computer, saving you time and effort as you work with Windows and other programs.  Most programs also provide accelerator keys that can make it easier to work with menus and other commands. Check the menus of programs for accelerator keys.  If a letter is underlined in a menu, that usually means that pressing the Alt key in combination with the underlined key will have the same effect as clicking that menu item. Pressing the Alt key in some programs, such as Paint and WordPad, shows commands that are labeled with additional keys that you can press to use them. Dialog box keyboard shortcuts. The following table contains keyboard shortcuts for use in dialog boxes. Press this key To do this: Ctrl+Tab Move forward through tabs...

Basic PC General Concepts and Terminology in Windows.

If you're not totally familiar with the various components of a modern PC, then this chapter will help you understand some of the common terminology used throughout the guide and what  each hardware component does in layman's terms. Note that I use a human body analogy to describe the function of C hardware components to hopefully clarify their functionality. Experienced PC users can skip this chapter. Bits and Bytes. You will often see the terms Bits, Bytes, Kilobytes, Megabytes and Gigabytes (or their abbreviations) being thrown around in guides such as this one. A Bit is the lowest form of computer information and  can take the value 0 or 1 (i.e. Off or On). All computer functionality is derived from the behavior of Bits. For our purposes, the main conversion factors you need to know are: 8 bits (b) = 1 Byte (B) 1,024 Bytes = 1 Kilobyte (KB) 1,024 Kilobytes (KB) = 1 Megabyte (MB) 1,024 Mega bytes (MB) = 1 Gigabyte (GB) Note in particular that the general con...
