In a single-player java2d game i'm making (first time) im getting disgusting rates of 5 frames per second when the current view is graphics-intensive, which slows the character to a crawl... I thought that the Images I had were ManagedImages since they were created through Component's createImage() but apparently these aren't fast enough. How can I *squeeze better performance* out of my java2d-based engine?

Arn't you meant to use createCompatibleImage() to get managed images?

You may be using some operation which is not accelerated, like translucency, compositing, antialiasing. Do a search on Java2D forum, there's plenty of threads covering this topic.

Finding out what is or isn't accelerated (or in the case of printing what causes the system to revert to using a big bitmap for the whole page) is something like playing a MUD. At least we get to cooperate, but it is way too hard to track down the details.

Maybe should create a wiki for detailing that?

Please fill out the information (provided by Abuse) that I started adding at "java2d" wiki page - someone good at wiki's should probably categorise it a bit better than I did too Grin

Currently accelerated Transparency is only possible using ManagedImages. (not with VolatileImages)

Also, currently only bitmask transparency is by default accelerated. However, there are flags to enabled hardware acceleration for images with a full alpha channel (Translucent). These flags also make AlphaComposite operations hardware accelerated.

The code to set the flags is :-

Code:

System.setProperty("sun.java2d.translaccel", "true");
System.setProperty("sun.java2d.ddforcevram", "true");

This Thread covers the flags in more detail http://www.java-gaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=2D;action=display;num=1048663269;start=0#0
