Resume:
I recently switched from the stable driver (173.14.12) to 177.68,
applied the tweads in the sticky thread to my xorg.conf, and performance
in general improved a lot. Smoother scoll in firefox, my X server not
completely hanging for some seconds every time firefox tries to load an
image, etc.
However, performance in terminal applications seems to be worse. With
the stable driver, sometimes performance when scrolling in konsole or
when using emacs in a terminal, was awful, but for some reason after
executing nvidia-settings -g it got fixed for some time, maybe two
hours as average, so I ended up having a loop in background calling
nvidia-settings -g every 30 minutes. Powermizer was always in mode 2
(maximum performance), before and after executing nvidia-settings -g.
With this beta driver, performance in the terminal seems to be always
bad, and it doesn't improve executing nvidia-settings -g. Furthermore,
sometimes serious glitches appear when scrolling in less or emacs, as
some lines don't get refreshed as expected, ending up with an awful mix
of old and new lines. In the stable driver usually scrolling down was
ok, but scrolling up didn't refresh the last line of the output,
sometimes the last two or three lines. Sometimes, there were lines in
the middle not being refreshed, but resetting the terminal seemed to fix
the issue. Now it's usually worse.
This happened in the stable driver but less frecuently, and always
happened in opera 9.52 when scrolling on any long website (well, I just
tried to reproduce it with the beta driver and it seems much better, but
scrolling is not as smooth as in firefox)
It may be related to the refresh problem that appears in firefox when
loading an image: if you're loading an image and its bigger than the
firefox window, it'll be resized to fit the window, but with the latest
driver, every time you load a resized image it'll appear almost black
(see: http://img28.picoodle.com/data/img28...gm_d33afc7.png). When you
click on the image to get the full size, it shows ok, and if you click
to resize it again it's still fine. This only happens if you have
focused the tab of the image while the image is loading. If you wait for
it to load in a background tab, when switching to the image tab the
image will appear fine right away.
Scrolling in xterm was and keeps being perfect.
