The first application that Red Mercury converted for full high resolution support was AcidSolitaire . Our goal was to keep the same screen layout, but provide higher resolution graphics for all elements of the game, including the color backgrounds. Fortunately, since we keep all of our graphics compressed when not in use, the additional overhead of all high resolution in-game graphics added only 4k to the overall size of the game. If AcidSolitaire detects it is on a high resolution device, it decompresses the high resolution graphics set, otherwise it leaves them compressed and out of the way. Low resolution is on the left.
High resolution looks better.
For those of you unfamiliar with Red Mercury games, you might be wondering why video performance would matter for a solitaire game in the first place. We end up playing a lot of solitaire, so we want the game to be very responsive. If it seems sluggish at all, it takes away from the fun of the game. Also, with automatic card movement and card dragging, the display has to refresh instantly, or the entire game has a muddy feel. Low resolution is on the left.
