Hi ,


Please respond is a stupid question but i need to understand !


If i well understood when you run in the main loop the command
GsGetActiveBuff() you receive the buffer that is not displaing in this
time so the drawing buffer, after receving this buffer index (0 or 1)
you alloc the packet for it and clear the OT table and than register in
the OT your commands, than wait for completition DrawSync(0) and for
VSync but.....

WHY you call GsSwapDispBuff that if i well understood swap the Draw buff
with the Disp buff  and than you run GsSortClear (if needed) and the
GsDrawOt that should be the command that do the real drawing. In that
way is not true that i'm drawing when the display of that buffer is
displaing, in other terms why we do the GsSwapDispBuff before the
GsDrawOt and not after ?????


Probably i havent understand something .....


Thanks

Luca
