Ah, that's me doing some magic on the leaderhead dds files! You see, there are two factors in play here that both make a difference for files that are otherwise the same (512x512) resolution:I meant individually. Each great person dds file is 256k while each leaderhead dds file is 171k. Except for hideyoshi, who breaks the trend with a leader file that is 341k. I would have thought the leaderheads would be much larger, but I guess there's more going on in there than I'd think.
1) There is no transparency involved in leaderhead files, unlike in great person popups. A transparency (alpha) channel outright doubles the file size.
2) Fortunately, GP popups aren't 2x size of the leaderhead files, as unlike the leaderheads, they never get zoomed in/out, and therefore need no MIP maps. Not as drastic as transparency, but it still reduces the file size by quite a bit.
With the amount of assets such as one RI has, I learned to use every trick in the book to keep the individual files as small as possible without compromising the quality too much.
