Description rozhuk.im 2019-06-18 21:35:18 UTC 
Looks like mem leak in x11/nvidia-driver, x11/nvidia-driver-340.
Then slim launch xorg it consume 6 gb (top: SIZE) with x11/nvidia-driver and 3 gb with x11/nvidia-driver-340.
On same config with amdgpu and scfb 100-300mb.

FreeBSD rimwks 12.0-STABLE FreeBSD 12.0-STABLE #0 r346795M: Sun Apr 28 01:43:38 MSK 2019     root@rimwks:/usr/obj/usr/src/amd64.amd64/sys/RIM_WKS  amd64
xorg-server-1.19.6_11,1

I already try with generic kernel and with empty device settings:
Section "Device"
    Identifier  "Card0"
    Driver      "nvidia"
EndSection


Now on my desktop:

I'm not entirely convinced that this particular problem should be addressed by the FreeBSD hackers rather than nVidia guys themselves.  Did you try to report it on their official forum?

Do you still experience this with the latest drivers' versions?  Also note that just the difference in the initial allocated memory does not necessarily implies that memory is/will be leaking.  Did you observe how these numbers change with time?
