I just loaded one of my terrain blocks using perfly. It shows the
texture processing info as follows:
PF Info: pfuDownloadTexList texture processing
PF Info: Initialized 1 Channel
PF
PF Notice: Using 60Hz video rate.
PF Loading texture:
PF File name = .../cib.int
PF Image size (SxTxR) = 2048x2048x1
PF Download size = 16777216 bytes
PF Download time =1314.261 ms
PF Download rate = 12.174 MB/sec
PF Total texture use = 16.000 MB
PF This texture uses = 100.000% of 16MB memory
PF Total texture use = 100.000% of 16MB memory
PF Download totals
PF Textures: 1
PF Elapsed time: 1.318 sec
PF
So now the question becomes, why is a 4MB image file taking up 16MB of
texture memory? Is it because my grayscale image is being duplicated in
the red, green, blue, and alpha bands? If so, I guess cutting it down in
smaller chunks will help.

Given sufficient time and money, all things are possible.
In lieu of time and money, caffeine and aspirin may also work.
