Part 1: Why PC Games Run Slowly

Are you inquiring why your PC gets super slow after a few hours of gaming? If your PC turns into a slug after a few minutes, it's probably because there's some memory leak or your hardware has gotten too hot. Here are some common reasons why games on your PC run slowly:

  • Excessive Heating Up of CPU & GPU

Your CPU and GPU work at their maximum capacity, and they often release heat. And if your cooling fan or thermal paste is not working properly, your computer will slow down to prevent permanent hardware damage.

  • Memory Leak Issue

The memory leak happens when a game is poorly optimized and forgets to clear temporary files from your RAM. As time passes, your game hogs more and more memory until your PC stutters, which leads to frame drops.

  • Outdated Graphic Cards

If your graphics card is outdated, that also slows down your PC, and running on it means your graphics card lacks the critical optimization patches required to run modern titles efficiently.

  • Background Apps

Other programs running in the background, such as web browsers with dozens of open tabs, antivirus scans, or multiple game launchers, compete with your game for CPU cycles and system RAM.

  • Old Hard Disk Drive

Running modern, asset-heavy games from an old mechanical Hard Disk Drive (HDD) instead of a Solid-State Drive (SSD) causes severe texture pop-ins and long loading screens.

If the Windows Game Mode is turned off, it also reduces your performance.

Part 2: How to Optimize Games for PC

There are multiple ways to optimize your PC for games and create a smooth gaming experience. By turning on Game Mode on your device, updating your graphics drivers, and lowering visual settings, you can reduce lag and increase FPS.

Other 8 Helpful Ways to Optimize Games for PC

Besides this, Windows offers some built-in features to optimize the PC gaming experience. Making some adjustments to your system's settings also enhances the PC performance and allows you to play smoothly. Here are some ways to optimize games for PC.

1.Enable Windows Game Mode

Windows includes a built-in feature that works as a free game optimizer for pc. It prioritizes game performance over background processes so you can play games without any interruption. Here is how you can do that:

Step 1: To begin with, you need to go to Settings from the start button. In the left pane, you'll see Gaming, click on it and then select the Game Mode.

Go to the game mode from the gaming option.

Step 2: This option will be OFF. Press it to turn On and optimize your system for gaming.

Toggle the Game mode ON to optimize your PC for gaming.

💡Tip: WMaster Cleanup's dedicated Game Booster tool can directly close all background apps so your system runs smoothly while you're playing games.

2.Turn On Hardware-Accelerated GPU Scheduling (HAGS)

Another way to prepare your PC for a better gaming experience is to turn ON the HAGS. By doing this, you allow your graphics card to manage its own memory by taking off the load your processor. Here's how you can do that:

Step 1: Open Settings from the start menu and then go to System and Display.

Go to the settings & system & Display.

Step 2: Now, you need to click on Graphics. Here you'll see the option for optimization for Windows games. Toggle it to ON to reduce latency and use advanced features in-game.

Turn on optimization for windowed games to get the best performance.

Note: You need to close and reopen the app for the aforementioned changes to take effect.

3. High-Performance Power Plan

To optimize your PC for gaming, you can turn on high-performance power plans. By default, our Windows settings are in a balanced mode, which saves power and ultimately the performance of the CPU and GPU. To change this setting in favor of improving your gaming feel, you need to follow these steps:

Step 1: Right-click on the Start menu and select Settings. Select the Power & battery. Now, from here, select the Power Mode settings.

Navigate to System, then Power and battery.

Step 2: To reduce the latency and input lag during gaming, make sure you adjust the drop menu to Best Power Efficiency.

Change the power mode to best power efficiency for optimization.

4. Increase NVIDIA Shader Cache Limits

By default, NVIDIA sets the cache limit to a modest driver default size. When you play multiple games, the system constantly overwrites older compiled shaders. This forces your PC to recompile them mid-game, causing unexpected frame drops and micro-stutters.

By lifting this limit, your system keeps shaders saved on your drive, leading to a much smoother gameplay experience when revisiting areas.

Step 1: Open the NVIDIA App on your PC and click on Graphics Global Settings Shader Cache Size option.

From the dropdown menu, change it from Driver Defaultto Unlimited or your desired size.

Go to NVIDIA and change shader cache size to your desired one.

You can turn on the shader compilation to reduce the frequency of game runtime compilation after the driver updates.

Turn ON automatic shader compilation to medium.

5. Move Games to a Solid-State Drive (SSD)

Mechanical hard drives (HDDs) are too slow for modern games that dynamically stream data into memory. Windows handles Xbox Game Pass titles via built-in system settings:

Step 1: Open your Windows Settings app (or press Windows Key + I). From here, you have to select Apps, and then click on Installed apps.

Go to apps from the settings and then select installed apps.

Step 2: Scroll down until you find the Xbox game you want to transfer.

Now, click the three dots on the right side of the game listing and select Move to move the game to your desired SSD.

Part 3: Best Practices for Long-Term Gaming Performance

To ensure that your PC is optimized for gaming, make sure your system is clean and ready. With a few adjustments in your system, like removing clutter and turning on the gaming mode, you can make your device ready to play games without any interruption.

Here are some best practices to optimize your PC for excellent performance in the long run:

  • Firstly, you need to ensure that your graphics driver like NVIDIA, AMD, or Intel GPU is updated for new titles and patches so you play games smoothly.
  • When you're playing games on your system, the hardware often gets hot, which cuts your frame rates. So make sure you every now and then remove dust from the case, fan, and heatsinks so that airflow remains optimal.
  • The startup and background apps take up a lot of RAM. Therefore, close background apps so that your RAM and CPU cycles are dedicated to your games only.
  • Don't fill your SSD to its maximum. Always leave 10% to 15%of your drive space free to ensure that the SSD can maintain peak read/write speeds and handle game updates efficiently.
