<p class="MsoNormal">Hello openjfx-dev,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Because Windows is very open hardware-wise, it is difficult to prepare the backend for all possible hardware combinations
<span lang="EN-US">available</span>, especially from <span lang="EN-US">performance perspective.</span> To make sure JavaFX performance does not degrade compared to old D3D backend we would like to call for volunteers to
<span lang="EN-US">help </span>performance-test the backend. These tests will let us get a general idea on how the backend behaves on different hardware and which areas of the backend to focus on
<span lang="EN-US">while </span>moving forward with optimization effort for Direct3D 12.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">At this point we tested the backend quite extensively on Intel-based integrated GPUs and did some testing on a machine running a recent discrete N<span lang="EN-US">v</span>idia GPU. We are primarily looking for testing
<span lang="EN-US">Direct3D 12 backend <b>on </b></span><b>a system running an AMD discrete GPU</b>, but any hardware combinations are welcome - the more the merrier :). Also note that these tests
<b>require a Windows machine</b>, as D3D12 backend is Windows-only.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">We run performance testing using RenderPerfTest JavaFX app</span> located in the JavaFX repository under "tests/performance/animation/RenderPerfTest".
<span lang="EN-US">I wrote a bash script to use with this app for performance-testing the backend</span>. The script will run all available demos on RenderPerfTest with a set amount of objects per test, average the FPS results from each
<span lang="EN-US">run </span>and output the results into a CSV file.<o:p></o:p></p>

3 runs each, for a single backend takes approximately 40 minutes - ensure your computer won't lock or turn off the screens during that process.<o:p></o:p></p>
