What are some faster alternatives to Java2d?

Question

I\'m looking to do some physics simulations and I need fast rendering in Java.

I\'ve run into performance issues with Java2d in the past, so what are the fast alternativ

Answer 1

My experience with Java2D is that it can be very fast, if you follow the rules. I had an application that went from 90% CPU to less than 5% CPU just by changing a few simple things. Using large transparent PNG's is a no no, for example.

A very good resource is the Java-Gaming.org forums: a lot of people, including the Sun 2D specialists, hang out there and provide many examples and solutions to performance issues for 2D drawing.

See: http://www.javagaming.org/ and then the topic "Performance Tuning".
