Wine 2.6 delivers on the long-awaited Direct3D Multi-Threaded Command Stream (CSMT) support, which should allow a number of Windows games to run much faster now under Linux. Additionally, Wine 2.6 has more Shader Model 5 support. There is also more support for 3D textures.
Other changes include better font transformations in DirectWrite and 25 known bug fixes.
After a lot of prep work, great to see CSMT appearing to finally land in mainline Wine as a big boost for those still relying upon some Windows-only game titles and is 3+ years in the making.
