Hello, I didn't find anything funky with the timers. They all seemed to be reasonable values. However, now that I'm running on one CPU, I get cases in which I don't get areas paged in. These seem to be around the same areas that used to hitch badly. I've created ways to change vsync interval, and multi-cpu dynamically. If I do either of these, then the area seems to page in, usually. So, I'm guessing that enabling vsync interval is doing something that pre-empts the paging from even happening. I say this because playing with the priority of the paging thread doesn't seem to help much.
Any ideas, or what I can try next? Thanks. By the way, I'm doing this while also porting to Linux to double my chances of success.

I'll just print out the available time every frame. Thanks for the idea.

Interesting obvservation, one could output how long each frame gives over to downloading graphics objects, if it suddenly shoots up over a couple of ms then you know what is amiss.
