As far as I have read the Geforce GTX1080 should run at at least 800k PPD or up to 1.3M .
However mine is doing right now 91296 PPD which is roughly 10% of what it should be able do...
It is working on Projekt 11750 right now.
In Task-Manager the copmute_0 says 0%
CUDA is at 98%
and 3D at ~5%
How can I start trouble-shooting?
Here a screenshot of GPU-Z sensor readings:

And General Graphics information from GPU-Z:

Thanks a lot!
