2. Keep Windows and My Video Drivers Up to Date

Make Sure Windows is Up to DateMicrosoft frequently sends out Updates to fix bugs, patch security issues, and add new services to the Windows Operating System. With the addition of Windows 10, updates are normally automatic but you can still access them and check if any new updates are waiting. Windows Updates may repair issues with your system that are causing freezes and slowness.

  1. Open the Start menu and select Settings.
click start then settings
  1. Select Update and Security.

  2. The system also may prompt you to restart, if it does, please do so at your earliest convenience, otherwise the update process will not complete.If you system was already recently updated, chances are that no further updates are available and your Update status will indicate: Your device is up to date.

Updating Your Graphics Driver

If you just purchased a new game or your current game is having issues running you may need to update your video drivers. Your video card uses the drivers to communicate with the rest of your system. New drivers often have bug fixes, new services, and updated settings.

3. Reduce Game Settings for Better Performance

Reducing Your Game's SettingsReducing the graphical settings of the game you're attempting to play reduces the demand it places on your computer's hardware, and can make a game playable, albeit a bit uglier from a graphical standpoint. Each game's graphical setting options will vary, and may still not make the game playable on your machine.

  1. Load the game you are attempting to play and navigate to the game's options or settings menu.
  2. Look for Video or Graphics settings. Depending on the game you are playing, the labeling of this menu will vary.

  1. Some games offer a simple menu that allows the user to set graphical options using a range. Settings may range from low all the way to ultra. Try reducing these settings below where they are currently set.
  2. Test your game. The reduction in settings may make the game playable. Reducing graphical settings may make the game look visually less appealing, but can be the difference between a game being playable or unplayable.

Graphics Settings and What They Mean

  • Resolution: The number of pixels that make up your game screen. The higher the numbers, the more power your game uses. Lowering this setting will greatly increase performance.
  • Anti-Aliasing: A setting that smooths jagged edges, making the game look better. Reducing this will increase performance while making your game look noticeably dated. Below shows anti-aliasing off on the left, and anti-aliasing set to four on the right. The jagged edges are more noticeable on the left.

  • Texture Quality: Textures are the pictures put over the models in a game. The higher the quality, the better the texture. The lower the quality, the faster the game will run. The image on the left has texture quality set to low.
An example of texture quality
  • Shadow Quality: Like texture, shadow quality determines how crisp and accurate the shadows in a game are, but they're much easier to set lower as you don't notice them as much. Lowering shadow quality may take out the shadow entirely or just reduce it to a dark circle. 
  • View Distance: Like it says, view distance is how far you can see in the game. It determines how far away things will be rendered. The shorter the view distance, the better the performance. The image on the left has the lower view distance.
View distance examples
  • Full Screen vs Windowed Mode: Full Screening your game may improve performance. This is because a full screened game allows the game to control the entire screen. A windowed mode game will have other simultaneous programs and settings running.

4. Close Unnecessary Background Programs

Your computer's central processing unit, or CPU, is arguably the most important component of any computing device. It handles basic instructions and allocates the more complicated tasks to other specific chips to get them to do what they do best.

Your CPU can age, get corrupted, have physical issues, or just not be up to newer tasks with newer technology.

You can check your CPU and see what processes and programs are using up its power by opening the task manager. You can then close items (hopefully after a bit of research as to what they are) to give more resources to your gaming.

  1. Press the CTRL + ALT + DEL keys on your keyboard at the same time.

  1. Select Task Manager.

  1. Select More Details at the bottom.
Task Manager with More Details highlighted.
  1. Select the Processes tab, then select CPU to sort the process list by how much CPU they use.
Task Manager with Processes tab and CPU field highlighted.
  1. Look through the top five or ten entries for programs you recognize.
  2. There will be many you don't recognize in the list; this is normal. Windows has a lot of processes, some with odd names, to allow it to run properly.
  3. If you see a program you know about and aren't using, select it, then select End task.
Task Manager with program and End Task highlighted.

You can check this information when you have your normal programs open. Open a few programs you usually use, and return to this window. See if you're using up your CPU for an extended period. CPU usage spikes are normal, but having your usage being above 90% indicates a problem.

The CPU is a physical part of your computer, not something you can download or modify through software. If you want to upgrade your CPU you need to contact the company you purchased your computer from, or a local technical support service. Depending on your device you may not be able to upgrade your CPU at all. If this is the case you will need to purchase a new device.

5. Boost Performance in Windows with Certain Settings

Change Power Settings to High PerformanceWhether you have a laptop or a desktop you have access to power settings in Windows 10. These tend to have more effect on laptops, but changing your power settings can affect your CPU power.

More power savings means trading some performance for less energy use. Lower energy use makes your laptop battery last longer, as well as makes your computer cost less to operate.

  1. Open the Start menu and select Settings.
click start then settings
  1. Select System.
System Settings
  1. Select Power & sleep on the left, then Additional power settings on the right.

  2. This setting will use the most energy, but will allow the computer to go as fast as it can at all time.

Disable Game Bar and Background Recording

Windows 10 includes a Game Bar that helps you record gameplay, share screenshots, and stream. It can negatively impact gameplay if you don't have the resources to share with it. Fortunately, you can easily turn it off.

  1. Open the Start menu and select Settings.
click start then settings
  1. Selecting Gaming.

7. System Requirements for Windows 10 Games

All games have posted system requirements. Ensuring that your machine can handle the demands of a game before purchasing is generally best.

System requirements list what type of hardware and software you need to run a game. Minimum requirements are just that, the bare minimum required to run a game. If you meet the minimum requirements the game will run, but it may run poorly. 

Where Do I Find System Requirements?

If you've purchased a physical copy of a game, the requirements are generally listed on the packaging. If you've purchased a game digitally, system requirements can be found on the marketplace they were purchased from, or directly from the game developer's website.

Here is an example of the Bethesda website displaying the system requirements for Doom:

How to Find Your Computer Specs

If Your System Does Not Meet the Requirements

When your system does not meet the requirements of a game you may be able to upgrade physical components like RAM or the video card.
