This is how I do tiled backgrounds.  :)  e.g. tiling with 32x32
sprites:

		...

	GsSPRITE blah;
	#define	SPRITE_HEIGHT 32

		...

	for( x=0; x<320 x+=SPRITE_HEIGHT )
	  for( y=0; y<240; y+=SPRITE_HIEGHT )
	    {
	    blah.x=x;
	    blah.y=y;
	    GsSortFastSprite(&blah,&WorldOT[activeBuff],0);
	    }

It is as fast as can be.  You should only have 1 GsSPRITE per 
TIM in memory.  There's no point in keeping more around since it
just consumes memory.
