Understanding Battle Net High CPU Usage

Battle Net, created by Blizzard Entertainment, is a popular gaming platform that allows players to access and play a variety of games such as World of Warcraft, Overwatch, and Diablo III. However, one common issue that some users encounter is high CPU usage when running Battle Net. High CPU usage can lead to decreased performance, system slowdowns, and even overheating. In this article, we will explore the causes of Battle Net high CPU usage and discuss potential solutions to alleviate this issue.

1. Background Processes and Services

One of the primary causes of Battle Net high CPU usage is the presence of background processes and services that are running simultaneously with the game. These processes and services consume CPU resources, resulting in higher CPU usage overall. Some of these background processes and services may be related to Battle Net itself, while others could be unrelated applications or system tasks.

To identify and manage these background processes, users can follow these steps:

  • Open the Task Manager by pressing Ctrl + Alt + Delete on Windows or Command + Option + Escape on macOS
  • In the Task Manager, navigate to the Processes tab
  • Sort the processes by CPU usage by clicking on the "CPU" column header
  • Identify any processes or services that are consuming a significant amount of CPU resources
  • Right-click on the process and select "End Task" to terminate it

Preventing Unnecessary Background Processes

To prevent unnecessary background processes from running during gaming sessions, users can take the following measures:

  • Disable startup programs: Open the Task Manager, navigate to the Startup tab, and disable any programs that are not needed to run on startup
  • Minimize system tray icons: Close or exit any applications running in the system tray that are not necessary
  • Disable unnecessary services: Open the "Services" application, located in the Administrative Tools folder in the Control Panel, and disable any services that are not required

2. Outdated Graphics Card Drivers

Another factor that can contribute to Battle Net high CPU usage is outdated graphics card drivers. Graphics card drivers act as a bridge between the operating system and the graphics card, allowing for smooth communication and optimal performance. Outdated drivers may not have the necessary optimizations and bug fixes required to run Battle Net efficiently, resulting in increased CPU usage.

To update graphics card drivers, users can follow these steps:

  • Identify the graphics card model: Open the Device Manager (Windows key + X, then select Device Manager) and expand the "Display adapters" category to view the graphics card model
  • Visit the manufacturer's website: Go to the manufacturer's website (e.g., NVIDIA, AMD, Intel) and navigate to the support or drivers section
  • Download and install the latest drivers: Locate the appropriate drivers for the graphics card model and operating system, download the latest version, and follow the on-screen instructions to install the drivers
  • Restart the system: After the installation is complete, restart the computer to apply the changes

Automatic Driver Update Tools

For users who prefer a more convenient method of updating their graphics card drivers, there are several automatic driver update tools available. These tools scan the system for outdated drivers and automatically download and install the latest versions. Some popular driver update tools include:

  • Driver Booster
  • DriverFinder
  • Driver Easy

3. Conflicting Antivirus or Firewall Software

In some cases, Battle Net high CPU usage may be caused by conflicting antivirus or firewall software. Antivirus and firewall programs are designed to protect the system by monitoring network traffic and scanning files and processes for potential threats. However, certain antivirus or firewall software can be overly aggressive or incompatible with Battle Net, leading to increased CPU usage.

To resolve this issue, users can try the following:

  • Temporarily disable antivirus or firewall: Temporarily disabling the antivirus or firewall software before running Battle Net can help identify if they are the cause of high CPU usage. However, exercise caution and only disable them for a short period to avoid leaving the system vulnerable
  • Configure exclusions: Add Battle Net and its associated executables to the antivirus or firewall software's exclusions or exceptions list. This allows the Battle Net client to bypass scanning and reduces CPU usage
  • Consider alternative software: If conflicts persist, it may be necessary to switch to a different antivirus or firewall software that is more compatible with Battle Net

Recommended Antivirus and Firewall Software

When choosing alternative antivirus and firewall software, users can consider the following options:

Antivirus software:

  • Norton AntiVirus
  • Avast Antivirus
  • Bitdefender Antivirus

Firewall software:

  • Windows Defender Firewall (built-in to Windows)
  • Comodo Firewall
  • ZoneAlarm Firewall

4. Insufficient Memory (RAM)

Insufficient memory, commonly referred to as RAM, can also contribute to Battle Net high CPU usage. When there is not enough RAM available, the system compensates by utilizing more CPU resources. This can result in elevated CPU usage and decreased performance.

To mitigate this issue, users can take the following steps:

  • Upgrade RAM: If the system has less than 8GB of RAM, consider upgrading to a higher capacity to provide more resources for the game and other processes
  • Close unnecessary programs: Before running Battle Net, close any unnecessary programs to free up RAM for the game

Alternative Aspects of Battle Net High CPU Usage

Besides the factors mentioned above, there are other potential causes of Battle Net high CPU usage, which are worth exploring:

1. Overclocking

Overclocking refers to the process in which users increase the clock speed of their hardware components (e.g., CPU, graphics card) to achieve higher performance. While overclocking can boost gaming performance, it can also result in increased CPU usage. If the CPU is running at a higher clock speed than it can handle, Battle Net may experience high CPU usage and instability.

To address this issue, users can revert their hardware components to their original clock speeds or reduce the overclock settings to a more stable level.

Monitoring Tools

To monitor CPU usage and clock speeds, users can utilize monitoring tools such as:

  • CPU-Z
  • HWMonitor
  • MSI Afterburner (for graphics card overclocking)

2. Background Downloads or Updates

Background downloads or updates can also contribute to Battle Net high CPU usage. When Battle Net is running in the background, it may prioritize downloading game updates or patches, which can lead to increased CPU usage. This is particularly noticeable if the network connection is slow or if multiple updates are being downloaded simultaneously.

To reduce CPU usage from background downloads or updates, users can:

  • Pause downloads: Open the Battle Net client, navigate to the game's download or update section, and pause any ongoing downloads or updates
  • Schedule downloads: Change the Battle Net client settings to schedule downloads or updates during a time when the system is not in use, such as overnight

3. Inadequate System Requirements

If the system does not meet the minimum requirements specified by Battle Net or the game being played, high CPU usage may occur. Inadequate processing power, insufficient RAM, or outdated hardware can all contribute to increased CPU usage.

It is essential to ensure that the system meets the minimum and recommended requirements for the game. If the system falls short, upgrading the hardware components may be necessary.

In Summary

Battle Net high CPU usage can be a frustrating issue for gamers as it can lead to decreased performance and system slowdowns. By identifying and managing background processes and services, updating graphics card drivers, resolving conflicts with antivirus or firewall software, and ensuring adequate system resources, users can mitigate high CPU usage in Battle Net. Additionally, considering alternative aspects such as overclocking, background downloads or updates, and system requirements can provide further insights into resolving this issue. By implementing these solutions, users can enjoy a smoother gaming experience on the Battle Net platform.
