Does not-indexed images files slow the game? - Tobruk - 03-01-2012
Hello. I have a question. Does not-indexed images files slow the game? Because when I edit sprites, I convert .bmp to RGB. It's not good? Maybe game will be slower?

I think it's the other way round, actually. Indexed files need to be mapped to RGB-colors to be displayed correctly, a calculation the non-indexed images do not have. However, the fundamental difference is that they're much smaller regarding their filesize compared to the RGB-images.
Either way, this only plays a role during the loading-stage. During the actual gameplay, there will/should be no difference.

still makes me wonder:
what makes the loading faster
smaller images
or less calculation

disk reads are usually much slower than the processor (discounting ssd-s). indexed file would probably require far fewer blocks to be read off disk than a non-indexed file hence saving time in IO. would say indexed file would be faster where larger file sizes are concerned
