1. Optimize Windows 10 With Gaming Mode

    2. Improve Online Game Performance: Disable Nagle’s Algorithm

    Nagle’s algorithm essentially bundles data packets at the cost of a smoother internet connection. It’s useful but having Nagle’s algorithm enabled on your computer may contribute to latency issues when playing games online.

    To disable this and improve gaming performance on Windows 10, start by checking your IP address:

  • Hit the Windows key + X keys.
  • Select Windows PowerShell.
  • Type in “ipconfig” and hit Enter.
  • Look for “IPv4 address” to identify your PC’s IP address
  • With the IP address noted, it’s time to edit the Windows Registry. However, be super careful before you make any changes to the Registry, as things can easily go haywire. Here’s how.

  • Head to the Start menu search bar, type in ‘regedit,’ and select the best match.
  • Select Registry Editor (tread carefully when fiddling with the Windows Registry)
  • In the address bar, copy and paste the following path:


    In the left-hand pane, you’ll see a collection of folders, with filenames comprised of letters and numbers. To access the correct file, match your IP address with the one listed against DhcpIPAddress in one of these folders.

    When you find your matching folder:

  • Right-click on the folder
  • Select New > DWORD (32-bit) Value
  • Name this TcpAckFrequency
  • Click OK
  • Select New > DWORD (32-bit) Value again
  • Name this one TCPNoDelay.
  • Double-click on each and set their parameters to 1
  • That’s it. Do this and you will disable Nagle’s Algorithm. If you run into any problems, reset the parameter values to 0, and they will be disabled.

    3. Optimize Windows 10 Online Gaming With Faster DNS

    If you’re playing online multiplayer or relying on a remote server for Windows 10 gaming, network traffic can cause problems.

    While upgrading to faster internet can help, it’s quicker and cheaper to just make some networking tweaks.

  • Hit Windows + I to open the Settings app.
  • Find Network and Internet > Change Adapter Settings.
  • Right-click on your wireless network.
  • Select Properties.
  • Highlight Internet Protocol Version 4.
  • Make a note of the two DNS entries for future reference.
  • Replace them with and
  • Click OK, and then select Close.
  • Restart your default browser.
  • Your internet should now be faster, which will help with online gaming.

    4. Disable Automatic Updates for the Best Gaming PC Settings

    Windows 10 will automatically update your OS and schedule a restart without your permission. While this feature doesn’t activate often, you never want to be caught unaware and risk your game save.

    Not only can automatic updates restart Windows without warning, but downloading updates in the background will limit your network connectivity.

    While you cannot disable automatic restart, it can be delayed. To reduce the chance of Windows Update downloads interrupting your gaming performance:

  • Open Settings with Windows key + I
  • Click Update and Security > Windows Update
  • Look for Advanced options then click Update Options
  • Disable Restart this device as soon as possible when a restart is required to install an update
  • Enable Show a notification (Windows will give plenty of warning when the system is going to restart following an update)
  • Use Pause updates to delay installation of updates for up to 7 days
  • By specifying when you’ll be using Windows 10, you can prevent Windows Updates from downloading and installing during active hours.

    5. Disable Notifications in Windows 10

    The Focus Assist feature in Windows 10 lets you specify how and when you receive notifications.

    Popups and chimes usually accompany notifications, but these can interrupt games. Focus Assist lets you manage what level of focus you devote to your work. To optimize your Windows gaming with Focus Assist, follow the steps below:

  • Hit Windows + I to open Settings.
  • Click System > Focus Assist.
  • Select Alarms Only to hide all other notifications.
  • Ensure When I’m playing a game is set to On.
  • That’s it. This will minimize the impact of notifications, making them available to check later.

    6. Prevent Steam Auto-Updating Games

    If you use Windows to play games, you’re probably buying and installing games via Steam.

    One of the largest annoyances with Steam is its update feature. This blocks you from preventing automatic updates across all your games. This may eat up memory by updating games you don’t play or limiting your network connectivity with background updates.

    To prevent Steam from updating games in the background:

  • Launch the Steam client.
  • Open Steam > Settings > Downloads.
  • Uncheck Allow downloads during gameplay.
  • You can also prevent Steam from downloading updates for largely unused games:

  • Open the Steam Library.
  • Right-click an underused but installed game.
  • Select Properties then Updates.
  • Under Automatic Updates change Always keep this game up to date to Only update this game when I launch it.
  • Ensure Pause background downloads while I’m playing is selected under Background Downloads.
  • With Steam correctly optimized, Windows 10 will be ready for AAA gaming.

    7. Tweak Windows 10 Visual Effects for Game Improvements

    Your computer’s graphical user interface (GUI) can be a hindrance to your processing power. By default, your Windows 10 appearance settings are set to impress.

    Games running in the foreground may conflict with a shiny GUI running in the background. Adjust these settings to optimize Windows 10 for gaming performance.

  • Open Settings with Windows key + I.
  • Type in “performance” and select Adjust the appearance and performance of Windows.
  • In the settings box, select Adjust for best performance.
  • Click Apply.
  • Click on the Advanced tab.
  • Ensure that Adjust the best performance of is set to Programs.
