Only if I don't use the nvidia setting change (ie, using the defaults
cause choppiness depending on the program). With the setting change, I
use no more than 35% cpu. Without it, I use a minimum of 45%, and
spikes up to 100%. nvidia-drivers-1.0.9746 . I haven't done any
further testing since switching to my new LCD 1080p, short of changing
my Xorg settings to full res. Today I just installed an xorg update,
we'll see how well the two jive together. I think Boston Legal was
notorious for causing chop, so I'll do some testing on it when the next
episode has aired.
