Important Features:
Async shader compilation (Avoiding shader compilation time)
Galop's DX11 Texture Encoder/Decoder (Improve Texture decoding specially EFB TO RAM)
Pre compiled Vertex loader & Optimized vertex decoding using SSSE3 and SSE4
Dolpby Pro Logic II support for xaudio and openal
Larger internal resolutions (IRx6) to allow 4k gaming
Custom Texture improvements to allow direct compressed texture loading including mipmaps
DSP - Time Streching Option (Improve sound output to avoid sound skipping on slow machines)
DX9 support for old machines
Modified Post Procesing interface to support:
-Multiple Stages allowing more complex effects.
-Depth and native gamma as inputs.
-DX11.
-Custom version of DolphinFX that work under dx11 and ogl
-SSAO and DOF.
-Texure Scaling Support
-Bump Mapping with advanced material properties (1)
-Phong Specular reflection to improve ligthing quality(1)

Other Features
Multithreaded Shader Compilation
Early depth test implementation to correct related issues and increase performance
Fast-Depth option now control the use or not of the accurate early z emulation so enabling fast depth will give a speed boos in some systems
Fast EFB Access. Implement global EFB Access Cache to reduce GPU stalls caused by CPU access to the efb (This option is Hack Tab in Gfx Options)
Shader generation Path reorganization to improve performance
Implemented 3d support for Side by side/TopBottom 3d rendering
Many DX9 old bugs fixes (ZComploc, Tev emulation, etc)
Others fixes and little improves.
