Source 2 is a 3D video game engine in development by Valve as a successor to Source. It is used in Dota 2, Artifact, parts of The Lab and in SteamVR Home. Elements of Source 2 are present in Counter-Strike: Global Offensive, such as Panorama UI. Source 2 was announced by Valve in March of 2015 at the Game Developers Conference and was first implemented into Dota 2 on June 17th 2015.

The engine is capable of rendering highly complex and well detailed scenes with minimal framerate drops, thanks to its new 64-bit support alongside Vulkan, allowing for better multi-core rendering and more efficient 3D rendering.

Valve has announced that Source 2 will be released to the public for free, and will only take money should it be used for commercial products.

Similarly to previous Valve game engines, it is still a very heavily modified version of the Quake Engine at its roots.

Allegedly Valve is currently working on three games with the Source 2 engine. (one of which is heavily rumored to be Half-Life: VR)


  • Supports both 64bit and 32bit systems.
  • Lower latency and more responsive input.
  • Increased performance limit to take advantage of higher end hardware.
  • Improved audio and voice processing.
  • Makes use of the Vulkan 3D Graphics and Computing API.
  • Native OpenGL support on all platforms.
  • New in-house physics engine, Rubikon.
  • New authoring tools, rebuilt from the ground up.
  • Physically based shading support.
  • Support for the Steam Audio sound system.
  • Enhanced GUI, designed to be more user friendly.
