Hello openjfx-dev, we just pushed a prototype of a new JavaFX Direct3D 12 rendering pipeline for Windows to a new "direct3d12" branch on jfx-sandbox. It is more than an experiment branch - we intend to fully develop the D3D12 backend there.
We're not necessarily looking for contributions at this point, but if anyone has early feedback about it or wants to try it by building it themselves, that would be fine. We also did not test it on a wider range of hardware, so your mileage may vary. While D3D12 pipeline will build by default, D3D9 pipeline is still the default pick at runtime. To run anything on D3D12 pipeline you need to force it with ex.: java -Dprism.order=d3d12 ... Backend supports 2D rendering (albeit with some graphical issues here and there that need to be ironed out) and basic 3D rendering. Expect not everything fully working yet (ex. some gradients on 2D controls are incorrect, or 3D-in-2D will straight up not work) and the performance not matching D3D9 yet. Our goal is to first reach feature completion and then focus on performance. Lukasz
