Well after doing a little digging it appears that a MBM hack should be possible , quote-
"The same applies to this feature. SDK/RTHMSharedMemorySample was added to RT about a half year ago too. _Special_ due to certain LCD manufacturers requests, to allow them to create their own software displaying RT's monitoring statistics on LCD.
Any man able to program can use this SDK/sample and can easily create MBM plugin."
The Sdk is located in the installation folder of rivatuner , so all you clever programming types can take a crack at it..PLEASE .
Henry i really hope you have a nvidia card ?
