1. I have a game which I'm trying to performance tune: I can obviously monitor how often I'm calling draw (draw rate), but I can't monitor how often the GPU is actually rendering (FPS) since the PerformanceTracker was removed from the JDK.
I'm running FX at full speed (-Djavafx.animation.fullspeed=true), and experimentation (using GPU vendor FPS monitors) shows that if I lower my "draw rate" to match the actual GPU FPS, I get marginally smoother rendering. I've never managed to work out why this would be the case, I get no errors in with Prism running in verbose mode, but if I call draw a faster rate than the GPU renders, I get tiny stutters in my game. These would appear to be missed frames. I can try to video the problem if necessary, but I can't easily make a simple SSCE. In short, I'd really like to see a new version of the PerformanceTracker in the public API. Is this difficult to achieve? 2. The other thing I'd love to see would be some way to set the native screen resolution in JavaFX: my question: https://stackoverflow.com/questions/50545263/setting-native-resolution-in-javafx All games offer this functionality in their graphics settings. 3. As, I last point: since I'm writing. It seems sad that Haxe Kha offers transcompilation into Java, but all they can compile into is AWT, which offers no shaders: hence there can be no Kha graphics4 in Java. Again, nods to some modernising of the renderer in JavaFX to enable pipeline support would be great. Best, Paul
