Java 2D Drawing Optimal Performance

Question

I\'m in the process of writing a Java 2D game. I\'m using the built-in Java 2D drawing libraries, drawing on a Graphics2D I acquire from a BufferStrategy from a Canvas in a

Answer 1

A synthesis of the answers to this post, the answers to Consty's, and my own research:

What works:

• Use GraphicsConfiguration.createCompatibleImage to create images compatible with what you're drawing on. This is absolutely essential!
• Use double-buffered drawing via Canvas.createBufferStrategy.
• Use -Dsun.java2d.opengl=True where available to speed up drawing.
• Avoid using transforms for scaling. Instead, cache scaled versions of the images you are going to use.
• Avoid translucent images! Bitmasked images are fine, but translucency is very expensive in Java2D.

In my tests, using these methods, I got a speed increase of 10x - 15x, making proper Java 2D graphics a possibility.
