My guess would be that it takes the "2048.9 MB" from dxdiag, interprets that as
"2048.9 MiB", converts it back to bytes (by multiplying with 1024 * 1024,
resulting in a value >= 0x80000000), and displays it as a signed integer.
Perhaps the value dxdiag returns should be in MiB, I'm not that familiar with
dxdiag, but the main issue seems to be that the tool display the value as a
signed integer for whatever reason.

IIRC WMI actually uses DXGI. I do know that the device names from
winex11/user32 and wined3d don't quite match up, but anything that originally
comes from wined3d should be consistent with each other.
