OK, those are good things to check.
I don’t have an optimus laptop; I have a Dell M4800 which has the Intel GPU permanently switched off (something about the controller for the high-res screen…) I had already looked through the Nvidia control panel and everything looks OK (CUDA GPU is set to all; tried changing it to the K2100m - no change in behavior; tried making an application profile - no change in behavior.)
Doesn’t appear to be set.
Which control panel are you referring to?
You’re something of a mind reader…! But unfortunately, deviceQuery and deviceQueryDrv both fail.
I’m about to try the 397.93 Quadro Notebook driver (I have 397.44 currently) and see if that changes anything.
