Source 2 Source 2 is a 3D video game engine developed by Valve as a successor to Source Source. It is used in Dota 2 Dota 2, SteamVR Home SteamVR Home, Half-Life: Alyx Half-Life: Alyx, S&box S&box, Counter-Strike 2 Counter-Strike 2, and much more.

Source 2 was first made public with the Dota 2 Workshop Tools Alpha in August 6th 2014 and formally announced by Valve in March of 2015 at the Game Developers Conference. It was then implemented into Dota 2 on June 17th 2015. Valve has announced that Source 2 will be released to the public for free, and it will only take money should it be used for commercial products.

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, Direct3D 11, allowing for better multi-core rendering, better graphics and more efficient 3D rendering.

Features

Limitations

Warning.pngWarning:Support for 32-bit, OpenGL, DirectX 9 (includes Direct3D 9), XAudio, and macOS versions below 10.14 were removed in 2021 with the Dota 2 Dota 2 update. SteamVR Home SteamVR Home is not affected. Newer games such as Half-Life: Alyx Half-Life: Alyx and Counter-Strike 2 Counter-Strike 2 don't support them.
Furthermore, newer games like Counter-Strike 2 Counter-Strike 2 will also require a CPU with SSE 4.2 support.
Warning.pngWarning:Some games like Counter-Strike 2 Counter-Strike 2 no longer support Squirrel, making things non-trivial to port and with no chance of a proper transition period when both implementations are functional.
