@jsmith_98: the two memory ranges reported in the `dmesg`
output are those reported by the graphics card via the BAR0/BAR1 registers in its PCI configuration space, i.e. BAR0, 16MB @ 0xfd000000 and BAR1, 128MB @ 0xe0000000. Which NVIDIA FreeBSD and Windows graphics driver releases are you using, respectively? Can you run the attached application via the commands below and post the output it generates? Has an earlier NVIDIA FreeBSD graphics driver release reported 128MB?
