Dota 2 system requirements and install guide (Windows, macOS, Linux)

Dota 2 is free on Steam and runs on Windows, macOS and Linux. Valve's store page lists minimum requirements only. It does not publish a recommended tier. The numbers below were checked on October 9, 2026 and can change.

Key takeaways

• You need about 60 GB of free storage on every system.
• 4 GB of RAM and a dual-core CPU at 2.8 GHz are the minimum.
• Windows needs DirectX 11. Steam itself now supports Windows 10 and later.
• A broadband connection is required.

How to install

1. Install the Steam client from Valve's website and sign in.
2. Search for Dota 2 in the Steam store and press Play Game. It is free.
3. Choose a drive with at least 60 GB free.
4. Wait for the download, then launch the game from your library.

Tips for older PCs

• Lower the render quality and turn off shadows and ambient occlusion in video settings.
• Close browsers and other apps while you play.
• Install the game on an SSD if you can, because loading is much faster.
• Use a wired network connection for steadier ping.

Languages and extras

The store page lists 28 languages. Full audio is available in English, Korean and Simplified Chinese, and the rest cover the interface. The Dota 2 soundtrack is a separate paid DLC, and a Remixes EP is free.
