Dota 2 Moves to Source 2 Engine

Earlier this summer, Valve announced a port of Dota 2 on the Source 2 engine called Dota Reborn which soon went into beta testing. Many new features were introduced most notably interface updates, engine improvements, and custom games. Yet, it was clear the developers had much to work on as numerous bugs and unfinished features were aplenty in Dota 2 Reborn. On September 9, the Dota 2 Reborn beta ended after nearly three months and has now become Dota 2.

The original Dota 2 client that ran on the Source engine was first revealed publically in November 2011. The major update earlier has removed nearly all of the Source version assets and its future is uncertain, though it rumored that some form of it may return as a replay viewer as the Source 2 version is not backwards compatible. From now on, Dota 2 runs in the Source 2 engine with native 64-bit support for compatible operating systems. For Windows, a DirectX 11 mode is hidden and enabling it offers no substantial benefit to the default DirectX 9 mode. Support for OpenGL is available making the game playable on Mac OS X and Linux including Steam OS. It is not known if DirectX 12 and Vulkan features will be implemented in the future.
