1. It turns out that 32 bit surfaces is an overkill in most cases. Good that there is 8 bit mode.
What evidence do you have of that? Have you done any benchmarking?
- how does the indexed image is generally rendered? Is it like: it sends index array to video card and the card makes substitution?
That would depend entirely on your system, and I would expect huge variations from one system to another. Even if using indexed images is a performance optimisation on *your* system, it's likely to be a pessimisation on someone else's. Personally I would forget about optimisation and only use indexed surfaces if it simplified my program logic. For performance, I trust convert() and convert_alpha() to know more about the system it's running on than I do. -- Greg
