Does not-indexed images files slow the game?

[Tobruk]

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?

[Silverthorn]

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

i should have known that

thank you
