Nvidia-smi support in 270.41.06

Question

I have an 8400GS and noticed that nvidia-smi no longer supports my GPU under 270.41.06?
$ nvidia-smi
NVIDIA System Management Interface -- v2.0
NVSMI provides diagnostic information for Tesla and select Quadro devices.
The data is presented in either plain text or XML format, via stdout or a file.
NVSMI also provides several management operations for changing device state.
Supported products:
Tesla: S1070, S2050, C1060, C2050/70, M2050/70/90, X2070/90
Quadro: 4000, 5000, 6000, 7000 and M2070-Q
Other: All other products are unsupported
All I can get out of it is Temperature and memory... it is unable to gather GPU usage info?
$ nvidia-smi -q

Answer 1

Seems to be the same around here with a 8600M GT. I had never used this tool before. It looks nice for scripting, at least for temperature and memory (can't get much more from it as well).
