GPU-Z Now supports Ati/AMD gpu memory usage.

[Final8y]

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

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.

Just checked my memory usage in Crysis running the central park bench run, max dedicated vram usage was 1545MB

Rumour that Afterburner will get the Mem feature as well.
