I tried to replace the 2048x2048 with four 1024x1024 and the performance decrease only hit when adding the fourth texture - makes sense because i have 64MB video memory on my intel X3100. So what do I do? I need this much space! Should I divide everything up into smaller textures so that only that texture is fetched from memory that is really needed and is also not so big? When playing around with four 1024x1024 i clearly saw that the one texture that was obviously swapped to system memory was much faster to get as the decrease was only down to 100fps and not 40fps. Or should I dynamically TextureAtlas.add() stuff?
