I’ve been designing a card game in Java on Windows. It runs really well on my laptop and a few others, but on a lot of other systems (even a few newer ones both Mac and Windows) the animation is incredibly slow.
I’ve found User Interface Toolkits for Java to be the best resource so far, but haven’t been able to make a significant improvement. I’m using the AWT/Swing libraries.
Looking at my game, (<1.5Mb), how could it be that on some computers (of similar spec) the performance seems to be significantly less that what it is on my laptop? The entire app is event-driven and I’ve done most of the optimization that I reckon could be done given the implementation.
I have a feeling it is memory-related. I create (compatible) and then store all my images into an array at the start, and then reference them there.
Note: I decided to make this game so that I can learn and practice some new ideas, so I’m not just trying to share it – I’m really interested to find out what’s going on here.
