What is Wine Staging?
Wine Staging is the testing area of winehq.org. It contains bug fixes and features, which have not been integrated into the development branch yet. The idea of Wine Staging is to provide experimental features faster to end users and to give developers the possibility to discuss and improve their patches before they are integrated into the main branch.
Wine Staging is maintained as a set of patches which has to be applied on top of the corresponding Wine development version. Package maintainers can decide if they want to include our full patchset, or only want to cherry-pick patches for specific bugs. Our current version includes fixes for about 450 bugs and over 900 patches total, and new patches are added frequently. Features and bugfixes available in Wine-Staging 3.8 are for example:
CSMT (Commandstream multithreading) for better graphic performance CUDA / PhysX / NVENC Support for NVIDIA graphic cards DXVA2 GPU video decoding (experimental) Direct3D 10/11 enhancements EAX 1 support Fixes for various upstream regressions GTK 3 theming support macOS preloader Performance improvements for IO-heavy programs and memory allocation functions S3 texture compression (DXTn) support Support for allocating more than 32 GB of memory Support for installing MSU files Various improvements to d3dx9 Various speed improvements (shared memory, RT priority) Windows ACL support
