my game is now using LWJGL but I have serious performance problems. The game runs only at 10 fps. What Am I missing? I use display list for each sprite I draw. What about Pbuffers do I need them? What is the equivalent of video buffers?

I know that calling Display.update() swap the buffers but I don't know more about buffers.

I've looked at the NeHe tutorials but didn't find something that helps me. I've also checked the red and blue books but I don't have time right now to read all the docs.

One question: did you compare the performance of Space Invaders between the Java2D and LWJGL implementations when running in window mode? On my laptop (S3 video card), the Java2D runs at 100 fps and the LWJGL at 45 fps. Why???

By the way, my S3 card has only 16 megs of vram.

Please help!
