NVIDIA

Hardware: (2018)
EVGA GT 730, 64 bit interface, 2gb ddr3, passively cooled.

note (2018/12/12): A hardware incompatibility in between an EVGA gt-730 and the DELL optiplex 3010 caused me to go radeon. Wishing I had figured this out sooner.

I get the best kodi-video playback when using Nvidia proprietary drivers, whether downloaded directly from nvidia and installed the hard way, or from RPMfusion.

Nvidia (but nouveau)

• Functions generally well, but hardware acceleration options were lacking, and tweak-yield didn’t justify the effort.
• Some television-stations play slightly choppy under nouveau (w/out hardware acceleration)

sudo dnf install mesa-vdpau-drivers libva-vdpau-driver libvdpau # hasn’t helped, but I gave up before pressing it.

NVIDIA (via rpmfusion)

proprietary driver installation via rpmfusion repositories

• beautifuller picture
• easier control of colorspace (than nouveau)
• not wayland compatible

Installation:

sudo dnf in \
xorg-x11-drv-nvidia \
xorg-x11-drv-nvidia-cuda \
akmod-nvidia \
libva-vdpau-driver \
libvdpau

Installing the proprietary driver directly from Nvidia

• best video playback
• creates a precarious situation regarding kernel support (and so is poorly suited for Fedora.)
• disallows secure-boot (unless unwelcome signing ritual)
• not wayland compatible

[ Installation Guide ]
I had previously blamed some audio issues on the proprietary drivers, but since then, I have found lightdm to be the culprit.
