My 64M graphics card shows about 4MB used, as expected.
Roughly: 600*800 = 'half a million'. Then 4 bytes per pixel and two buffers.
Why does yours show 22MB used? It's hard to say. I assume it's just the way the driver manages things. Maybe it allocates a block of memory to itself as a kind of graphics 'swap file'.
