Awesome, I discovered that if I use bigger page sizes, my level would display much more smoothly.
Not because bigger page sizes are better, but because the code i was using to update my indirection table was god awfully slow!
(and the bigger the page size, the smaller the indirection table)
In the crytek paper they mention a trick where they basically render their page changes into the indirection table instead of uploading a texture.
Sounds like the next step for me!
Now if only I had some time to actually do this.. hmmm
Oh and defrag your harddisk when working on virtual texture tech!
