That’s very interesting info !
Now, I would love to have some more details on when HW acceleration is in use and optimal (and/or what sort of “system” config we need to make on Linux to make it work).
I need to choose the HW for a dedicated netbox running a JavaFx application, and for now the only solution I see is to test different HW until I find the one that works perfectly with JavaFx…..

Thanks for the info, Dmitri.
So no wonder, I have a Nvidia graphics card, but as I said, an old one: GeForce4 MX 4000
I have JDK 1.6.0_13, but not a good enough card, I suppose.

Philippe, the current implementation (as of JavaFX 1.2) requires Pixel Shader 3.0 level of hardware for JavaFX hw accelerated pipeline (and it also requires JDK 6u10+), and it’s only enabled on Nvidia and ATI video boards, Intel ones are excluded due to driver stability and performance issues.

Oh great, except for a few intrinsic methods (obviously Identity and Flood, for example), I have only CPU/SIMD on my old Windows XP box. According to dxdiag, I do have Direct3D 9.0 working. Although according to my JGears tests it is excruciatingly slow (1 or 2 FPS with the translucent gradient texture) when OpenGL performs at a decent rate (around 45 FPS). So I wonder why we don’t have OpenGL acceleration on Windows platforms.

Depends on your definition of “support”. Shaders are used for implementing built in effects. They aren’t exposed to the developers (yet).

Steven, so the conclusion is if I have a GPU, JavaFX will be accelerated with the GPU always? But JavaFX (still) does not support shaders, it is that right?.

I have the same results since first version
