Java2D Performance in 1.5 Beta

Java 2D
#1

I’m curious, for those of you who are working with Java2D in the 1.5 Beta release, I have two questions:

  1. Are you seeing a significant drop in CPU load (as a result of off-loading graphics operations to the video card) with the OpenGL pipeline, as expected?

  2. How much did you have to alter your code to take advantage of the new pipeline? This is the question I’m especially curious about. I’m already using ImageIO to load images, and I’m using BufferStrategy to do rendering in 1.4.2. How much “porting” code will I have to write get the most of 1.5?

Thanks in advance for any input.

ogl pipeline for windows isn’t in beta1, trembovitski has said it will be available in beta2 (which itself will be available very very very very soon)
Dunno about other platforms…

Chris Campbell reported me some nice numbers about ogl acceleration in B2/win. Let’s wait for the public release which will be “REAL SOON NOW ®” :smiley:
