A lot of renderer refactorings allowed to implement a working Vulkan backend. Currently some shaders might be missing (report if you got a message). The main thing to test is the patch on different hardware and different GPUs.
Vulkan should make performance of the game more stable and predictable. In some cases even faster, but not everywhere as we use it in a single thread.
Shaders aren't going to be committed yet. To run the game you need to download them separately from here (mod):
Known issues (will be fixed during FF):
- Screenshots, not implemented yet
- Some shaders might be missing
- macOS isn't supported yet (but planned)
