With it set to on, its failing AP-27 WU crunching. Set to off, WU proceeds fine. Possible bug?

I don't have such a setting. If I did, I'd have tried it.

There's no drop-down menu item for the control panel on my Windows 7 system. GTX 1060, so not old.

I know there USED to be an Nvidia control panel, but I haven't used it in years and if it's here, it's hidden well.

I have a GTX 1060 3G.

Although the Control Panel manual for my driver version states there is an "Optimize for Compute Performance" feature (top of page 21), that option doesn't show up for me.
Maybe it's because I've installed the driver only with no additional features (PhysX, etc).

Anyway, please see the note regarding Optimize for Performance in the above referenced manual:

Windows 10, Maxwell
GPUs and later.
Offers significant improvement for some Compute applications.
Care should be taken when turning this setting ON, as there can
be unpredictable effects with some applications and graphics features.


Edit:
In case it matters, I've manually stopped these services (and set them to manually start):
NVidia Telemetry Container
NVidia Maintenance Service.

NVidia Control Panel will not start if the NVidia Maintenance Service is stopped.

Because I was bored...

From NVIDIA (on 01/25/2017):
"This setting is intended to provide additional performance to non-gaming applications that use large CUDA address spaces and large amounts of GPU memory when run on graphics cards based on second-generation Maxwell GPUs. Graphics cards based on other architectures do not utilize this setting. "

From a gforce.com forum, it was released in driver version 378:
Changes in Release 378
Added new setting in the Manage 3 Settings page - Optimize for Compute Performance.
Applies to Maxwell GPUs under Windows 10.

From a random redit thread:
"just a quick heads up: this option doesn't appear in pascal cards, such as the nvidia 10xx series"

From Wikipedia:
Second generation Maxwell (GM20x) Chips:
GM200
GM204
GM206
