This project is an attempt to convert Direct3D 9 programs
to Direct3D 11.
It reimplements the d3d9.dll, which contains the core D3D9 interfaces.
Most D3D9 games are CPU limited on modern PCs, since GPU power increased exponentially while CPUs fell behind. Furthermore, most (old) games lack multithreading support, draining the CPU resource even more.
This project uplifts the games D3D9 graphics API calls to D3D11.
Note: the project is currently under heavy development. Currently, it is not capable of running real games. You are welcome to build and test it yourself if you want to.
Important: this project should be used together with DXVK, which would then translate D3D11 to Vulkan. Without DXVK, this project will probably not provide any performance improvement, more likely will degrade performance.
Read the documentation online on GitHub Pages!
All of the project's documentation is stored in the docs directory and is checked into the repository.
We don't use GitHub's wiki pages, because it is hard to contribute and review changes to the wiki documentation. It is better to use pull requests for documentation changes.

After installation, see the usage instructions.
-
Wine for allowing us to run Windows programs on other OSes
-
DXVK for inspiration and making this project possible
-
VK9 for the original D3D9-to-Vulkan wrapper
