Coming hot on the heels of Wine 2.1, on which it’s based, the Wine Staging 2.1 release has revamped the CSMT (Command Stream Multithreading) patchset, which is the application’s number one functionality, used for using the available GPU (Graphics Processing Unit) and CPU (Central Processing Unit) more efficiently by moving the execution of OpenGL commands to a separate thread, to support Direct3D 10 and 11. CSMT is what makes Wine Staging so special, and why users choose it instead of Wine 2.0. The development team worked very hard on some new technologies that would speed up the rendering, and they promise to add more performance improvements in the next versions. Other than that, Wine Staging 2.1 adds support for certain processor group functions and resolves many of the issues left out from the Wine Staging 2.0 release.
