Model 4, made possible by new graphic chipsets as GeForce 7 or Radeon X1xxx series, allowed for improvements in graphic effects. Developers of this era of 3D engines often tout their increasingly photorealistic quality. Around the same time, esports we're beginning to gain attention. These engines include realistic shader-based materials with predefined physics, environments with procedural and vertex shader-based objects (vegetation, debris, human-made objects such as books or tools), procedural animation, cinematographic effects (depth of field, motion blur, etc.), high-dynamic-range rendering, and unified lighting models with soft shadowing and volumetric lighting. However, most of engines capable of these effects are evolutions of engines from the previous generation, such as Unreal Engine 3, the Dunia Engine and CryEngine 2, id Tech 5 (which was used with Rage and makes use of the new Virtual Texturing technology). The first games using Unreal Engine 3 were released in November 2006, and the first game to use CryEngine 2 (Crysis) was released in 2007. Early 2010s: Graphic technique mixes Further improvements in GPUs like Shader Model 5, made possible by new graphic chipsets as GeForce 400 Series or Radeon HD 5000 series and later, allowed for improvements in graphic effects. such as Dynamic Displacement Mapping and Tessellation. As of 2010, two upcoming evolutions of major existing engines had been released: Unreal Engine 3 in DirectX 11 which powered Samaritan Demo (and which is used with Batman: Arkham City, Batman: Arkham Knight and more DX11 based UE3 games) and CryEngine 3, which powers Crysis 2 and Crysis 3''. Few companies had discussed future plans for their engines; id Tech 6, the eventual successor to id Tech 5, was an exception. Preliminary information about this engine which was still in early phases of development tended to show that id Software was looking toward a direction where ray tracing and classic raster graphics would be mixed. However, according to John Carmack, the hardware capable of id Tech 6 did not yet exist. The first title using the engine, Doom, was released in mid 2016. In September 2015, Valve released Source 2 in an update to Dota 2. See also Game engine List of game engines List of first-person shooter engines References
