Unfortunately I tried this and it doesn't work. JavaFX has a dual threaded architecture in which all app logic and scene graph handling happens on the app thread, and the process of drawing a frame actually just pushes commands onto a render thread which then does the work of translating into OpenGL or DirectX or whatever the underlying rendering engine is. Exactly what that data stream looks like I'm not sure, but my guess as to what is happening (didn't profile it yet) is that my app does lots of stuff during startup (including starting other threads, networking events, etc) and the OS doesn't know that the Prism render thread is special, so it doesn't get scheduled with higher priority vs the others. If there was a way to synchronize with the render thread, that would work, and if there was a way to make the render thread higher priority than the rest, that might also work. But I'm not enough of a guru (yet) to know the best way to do this.
