--- Comment #4 from rkoberman@gmail.com ---
As I mentioned, I have the VirtualBox 6.1.20 guest additions installed, so that
is not the problem. I am running on a CometLake i5-10210U CPU and GPU in a
Lenovo L15. I am running the latest drm-13fbsd-kmod.

You first suggestion was right. It is that I have 3D Acceleration on. Once I
turn it off, I can set the display to VBOXSVGA. It simply could not be selected
with 3D enabled. With VBOXSVGA and no 3D, I get between 1780 and 1980 fps.
There is a big hit on the CPU, of course, but is is a big win. Also, the system
boots up much faster and login is faster. With 3D and VMSVGA, it took several
minutes to boot and about 3 minutes just to login.

Thanks so much! Unless there are further suggestions in the next couple of
days, I'll close this, though the lack of 3D acceleration is disappointing.
