I was waiting for this NV_primitive_restart a long long time and i was so disapointed by the multi_draw_arrays EXT from the guys @SUN 
Anyhow, i would like to know if this great extension (which took time (almost 3 revs) to our favorite engineers will be possibly supported (without emulation) on earlier version known as NV1x and NV2x families?? (matt,mcCraig?) 
Moreover and now it is completely different i have seen an extension called WIN_swap_hint in the papers but no spec attached as it is win32 related. 
any infos?
thx!
