Hanit, are you seeing some performance problem ? Does the paging seem to
slow you down ? It shouldn't. The great thing about clipmapping/iR is
that there is the bandwidth to cache the various levels of a clipmap and
keep trickling in new texture to the TRAM around you as you need it, I
would always expect to see this texture trickle in a clipmapped app,
it's what makes clipmapping superior to other methods like paging in big
tiles at once as you need them, the paging is controlled and low enough
overhead to not suddenly hit your frame rate. Are you seeing something
that doesn't sound like that ? I guess that in your hi-res inset you
have everything cached and don't page until you move into the low-res
area with presumably larger textures/more levels.
Cheers
Rob
