How is the 1.3 crop of the new Nikon D500 camera accomplished? Is it done in software, or is there optics?

In camera crop is achieved by reducing the number of pixels used to capture the image. In this car it results in a 2.0X net crop factor which yields an image the same as a M4/3's sensor would give.

The number of pixels is not related to the crop ratio. That is determined by the physical size of the sensor in relation to 35mm full frame. This illustrates that relationship.

In my opinion unless the camera provides an increase in frame rate (fps) when shooting in the crop mode, there is no advantage in doing this.
Its the same as cropping but not as flexible since the view is fixed.
I don't believe the fps increases in the crop mode on the D500.

Of course it is.
Here is the formula:
Total Sensor MP divided by the square of the crop factor.
example: 20(MP)/1.3 squared=11.8MP

What you are referring to is cropping in pp, but in the camera, the crop factor is decided by the sensor size as was mentioned before!

Not really what I was asking.
I wanted to know how the additional 1.3 crop factor (on top if the 1.5 previously available in some FX cameras). The D500 has two crop factors that multiply out to 2.0.
Is the camera just scaling up from two different crops of the FX sensor? Or is there some other explanation?

The D500 is already a 1:1.5 crop camera. The additional 1.3 crop just uses electronics to select the central part of that sensor. No optics involved, so there's no benefit in image quality over just cropping more selectively on your computer later.

The camera is just using part of the sensor when in that mode. That is all there is to it.

YOU ARE VERY WRONG, MY FRIEND. Same as Canon has on their cameras such as IDIV, multiplier of 1.3, not 2.0, which is a huge difference.

You are also WRONG (the TOTAL crop factor is very close to what MTSHOOTER said, actually 1.95X) Try multiplying 1.3 X 1.5... Remember that the 1.3X is "on top of" the 1.5X that is NATIVE to the D500 (and all of Nikon's other DX cameras).....

Please refrain from commenting when you have no clue as to what the answer is. The thread has nothing at all to do with Canon cameras nor their 1.3X APS-H crop sensor.
