I've been meaning to post this here for a few weeks now and kept forgetting. As of Beta 7 of the 2.2.0 release of MSI Afterburner, the monitoring program now has the ability to report memory usage for ATI cards. Memory usage for ATI cards was previously an NVIDIA only feature.
Added unified vendor independent videomemory usage monitoring layer for graphics cards, having no generic videomemory monitoring interfaces implementation in display drivers. Unified videomemory usage monitoring layer is based upon RivaTuner's VidMem plugin technology under Windows XP and original concepts of accessing Direct3D kernel mode thunk statistics under Windows Vista and Windows 7, introduced by Mark Russinovich in ProcessExplorer 15. By default unified videomemory usage monitoring path is enabled as primary ath on AMD graphics cards and as a fallback path on NVIDIA graphics cards when generic NVAPI videomemory usage monitoring is not available (e.g. on NVIDIA graphics cards unattcached to Windows desktop, such as dedicated PhysX or other GPGPU graphics cards). Power users may redefine unified and generic videomemory monitoring paths usage behaviors for both AMD and NVIDIA hardware abstraction layers via the configuration file.
