The latest GPU-Z 0.55 now supports graphics card memory usage.


LINK


Memory Usage (Dedicated): graphics memory pages occupying the GPU's memory (memory on the graphics card)

Memory Usage (Dynamic): graphics memory pages occupying the system memory

In case of Radeon IGPs, "GPU's memory" would refer to the UMA area of the system memory, and "system memory" would refer to the OS-addressable system memory apart from UMA area.

GPU memory usage can also be displayed in osd when using techpowerup's osd server.

Nice, i always wondered how much actual gpu memory was being used. Great new feature. +1

Must have missed it, but this thread also shows how to monitor it in game using osd :p


EDIT:


Looks like it'll be supported in MSI afterburner pretty soon too.



Done. Got access to "hole" working on my primary rig. The PC is NVIDIA GPU based so I can compare OS videomemory usage performance counter with native NVIDIA videomemory usage reported via NVAPI. The results for both paths are close. NVAPI reports a few MB more in use than performance counters accessed throgh the "hole", but considering that delta between the results remains fixed under the load I'd say that performance counter results are pretty accurate and can be just a few MB off (probably minus some additional driver caches seen to NVAPI but invisible to the counter).
Will test it on AMD soon (but see no reasons why it wouldn't work, becasue implementation is vendor independent) and report the results.

P.S. The path is specific to Vista/W7 driver model, so it won't work under XP for sure. However, I could get it working under W7 only, but not under Vista (ProcessExplorer and GPU-Z gave the same result, i.e. no videomemory usage monitoring).
