Ok, I've confirmed that it is the CPU, because if I move the terminal
window to the side, so that it's not covering the mythfrontend screen
anymore, the choppiness returns.
I adjusted the slider in nvidia-settings, under the OpenGL section
all the way to max performance, but that didn't resolve it. I didn't
find any other sliders in other categories.
Are there other tips for increasing performance?
Thanks,
Pete
