directx 9.0c registry problem

Last Modified: 2008-05-23
I have a directx 9.0c problem with it reporting the "Approx. total memory: n/a".

previous elements of the problem to narrow it down to directx registry settings, are detailed here:

I just loaded an old registry backup to the machine.
It caused a lot of problems, but dxdiag did report everything correctly, and the software in question worked.

loading the harddrive backup now, for fairly "clean" slate to begin the registry debug on.

I could use some help with what registry keys to look for.
I have CompareIt! v2.89 for side by side registry comparison.
