Compatibility Testing for PC Games: A Full Guide

EXPLORE A FULL GUIDE ON COMPATIBILITY TESTING FOR PC GAMES TO ENSURE YOUR GAME RUNS SMOOTHLY ON VARIOUS SYSTEMS.

What is Compatibility Testing of PC Games?

Compatibility testing, at its core, is a type of non-functional testing conducted to ensure that your apps or games are capable of running on different environments. This includes but is not limited to different hardware configurations & operating systems, different types of screen monitors, as well as various software applications, different network environments, different terminals, different languages, and so on.

When it comes to the compatibility testing of PC games, its scope usually narrows down to the following 3 types:

1. Hardware Compatibility: This involves testing the game on different hardware configurations. It includes different types of processors (CPU), graphics processing units (GPU), memory (RAM), hard disk capacities, and screen resolutions. The objective is to ensure that your game performs optimally across all these different setups.

2. Software Compatibility: This involves testing your game over different operating systems (like Windows 7, Windows 8, Windows 10, Windows 11, etc.), and antivirus software, input methods, and DirectX versions. The goal is to guarantee that your game runs smoothly, regardless of the software environment.

3. Language Compatibility: Apart from English, your game may have players from different regions who speak Chinese, Japanese, French, Spanish, and other different languages. Testing your game in various languages ensures that all text in the game is correctly displayed and understandable to players, regardless of their language.

Note: For games that run on other devices or platforms, they also need to do console devices, or other kinds of compatibility testing. For example, players nowadays expect games to be released on their preferred platforms. It’s not uncommon to see players criticize a game on social media if it fails to launch on their devices during a global release. As a result, developers need to ensure that their game is compatible not only with PCs, but also with devices like PlayStation, Xbox, and Switch.

Why Compatibility Testing of PC Games?

Good compatibility testing helps you REACH MORE USERS.

For developers, it’s essential to ensure that your PC games can have a good performance on all popular terminals, which prevents potential harm to user experience and loss of players. That’s why it’s crucial to conduct compatibility tests on various PC devices. By doing so, you can identify compatibility issues early on and fix them promptly, ensuring a smooth gaming experience for all users. Consequently, it leads to heightened customer satisfaction, broader market penetration, and an expanded user base.

However, it could be highly challenging if you choose to do it within your own team:

1. Unable to guarantee full coverage: with so many and diverse device brands, OS versions, and PC screens on the market, it‘s challenging to guarantee that the game product is compatible with most PC devices.

2. Lack of professional QA testers: this slows down the testing process, results in uncomprehensive compatibility testing, and hinders the launch of your product.

3. High costs to get expert testers: Hiring a seasoned tester can be very expensive! Balancing the cost of expert testers with the need for thorough testing might give you a headache.

4. High costs in equipment purchase, updates & maintenance: Ensuring compatibility requires a substantial investment in acquiring various devices, keeping them up-to-date, and maintaining them in optimal condition. This can drain your resources and budget.
