Dota 2 is a game loved by every player. However, it is recently that several players have faced the Change Rendering API error while trying to launch the game. When a user clicks “Play,” the error message stops it from loading. While it is just a normal error and can be fixed, it often frustrates users as they do not know what it is about.
The Change Rendering API is a launching issue with Dota 2 that can be resolved using the game launch options. In this post, let us look at the error closely and try to understand why it appears and how you can fix it.
Without further ado, let’s get started!
What is the Change Rendering API Error in Dota 2 About
The rendering API for any application refers to its processing API that interacts with the program to run it successfully. It has much to do with your PC’s graphic memory and processing capabilities. The most commonly used rendering files in games are your DirectX files. These files assist a game in rendering the visuals properly, enhancing your overall experience.
With that being said, some of the main reasons that this error appears include –
- Game Launch Misconfiguration
- Outdated GPU Drivers
- System Glitch
If there is just a glitch with your PC’s display or processing capabilities, you can simply go ahead and fix the issue with a restart. It can happen to an older PC you have been using for a while. However, if you feel that the core reason behind the error appearing on your PC is not a glitch but something else, you might have to use stepwise fixes. Find them in the next section.
