How to fix Dota 2 Change Rendering API error

Before running the game, you can use the Game Launch Options feature on Steam to change game settings. Launch options allow the user to supersede the internal settings of the game. This is an effective means to recover from incompatible video settings and well as troubleshoot a wide range of issues. So in order to get rid of the error message, you should set a launch option specifically for Dota 2. Here’s how you can do this:

1) Under the Library in Steam, right-click on your game title Dota 2, and select Properties.

It’s recommended to run your game on dx11. But some older hardware doesn’t support dx11 so you would run it on dx9. You can simply type -dx9 instead of -dx11.

4) Close your game’s Properties window and your problem should be solved. Till then launch your game.
