<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>In my opinion this is a nice change.</div>
<div>Modernizing the Windows backend of JavaFX is a good idea and will also enable us to use more modern features if needed.</div>
<div>There should be some performance improvements as well.</div>
<div><br/>
Even though Direct3d9 works and is not deprecated, I still think it is good to move on with the technology.</div>
<div>I guess that at one point (when everything is more stable and tested), the direct3d12 backend will be enabled as the default?</div>
<div>When I have some time, I will check it out as I'm curious myself about this.</div>

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