I have been happily working on my game using delphix for some time and it seemed pretty good, because I mainly used its draw procedure, but when I decided to use transparency for explosions even with my 1.4GHz thunderbird with just one transparent sprite onscreen the frame rate dropped below my desired 50. I checked some other components, but those that were fast with transparency were very buggy like omega. Maybe I should try doing it with openGl, but I can't find a simple 2d example for it. So what is the best for 2d ease of use/performance wise?
