That's the problem. Not all devices' displays are portrait. The iPaq 3630 display is actually a landscape display, so as you increment the buffer you are actually stepping up the screen (when viewed in the natural portrait orientation). So a portrait buffer will cause lots of cache misses during the blit on that device. The issue is more pronounced on some devices than others.
Game libraries like GapiDraw align all their internal buffers to match whatever the device is, so the gapi blit can just be a simple memcpy. (to my knowledge)

Hi,
Is there a list somewhere that shows what equipment the developers have?
Would it be a handy idea or not?
As for me my ppc's are:
Toshiba e740 (WiFi) (400mhz xSacale)
Audiovox PDA-1032 (good for limited memory testing)
Just sold the h1910!!
iPaq h3850 (CF & battery sleave)
All are running ppc 2002 but the HP upgrade to 2003 for the 3850 should be showing up in a few days.
The Audiovox and h3850 both have the SanDisk CompactFlash WiFi card.
Anyone need to test on any of these just let me know.
