Hello everybody,
I browsed through the forums and I see several people encountered same
problems as me with 11.0 and 11.1.
The problems are:
- Unresponsive GUI in general
- Choppy and slow resize of windows
- Slow scrolling
- Slow terminals
- Slow Firefox in general
- Firefox choking on javascript effects (fade in, fade out, and such)
or fixed backgrounds - To define: SLOW 2D PERFORMANCE
Good test is to go to:
‘Getting Started with Firefox’
(http://en-us.www.mozilla.com/en-US/firefox/central/) and click on tabs
(Work, Learn, Play, Connect). If content fade in/fade outs are smooth,
then you are good to go, and if they are choppy and bring your CPU to
knees - and you have a Nvidia card - this is the post for you.
I finally got around to what the problem is:
N-v-i-d-i-a- -p-r-o-p-r-i-e-t-a-r-y- -d-r-i-v-e-r-s- -w-o-r-k-
-t-e-r-r-i-b-l-y- -b-a-d-l-y- -i-n- -2-D- -w-i-t-h- -n-e-w-
-g-r-a-p-h-i-c- -c-a-r-d-s- -(-s-e-r-i-e-s- -8-x-x-x- -a-n-d-
-9-x-x-x-)-,- -a-n-d- -s-o- -d-o- -n-v- -a-n-d- -n-o-u-v-e-a-u-.-
Using gtkperf (‘GtkPerf’ (http://gtkperf.sourceforge.net/)) - a simple
benchmarking tool to measure 2d performance I got about the following
results for 100 iterations:
nv drivers: 18 seconds
nvidia drivers: 16 seconds
vesa drivers: 10 seconds
That should give you an idea about the quality of both nv and nvidia
drivers. 3d works about right with nvidia.
Anyway, after some googling, I stumbled upon this link:
‘nVidia 8000/9000 Series Performance Issues - nV News Forums’
(http://www.nvnews.net/vbulletin/showthread.php?t=115916)
I suggest everybody with those problems to read through it.
Doing the following really quicked up my nvidia drivers:
Code:
nvidia-settings -a InitialPixmapPlacement=2 -a GlyphCache=1
(make a script out of it and execute it on your DE startup)
and adding:
Code:
Option “PixmapCacheSize” “300000”
Option “OnDemandVBlankInterrupts” “True”
to my xorg.conf “Device” section.
This is another interesting reading:
‘» 2D benchmarks on Linux Nvidia, Intel, ATI: xrender on Jkx@home »
Blog Archive’ (http://www.larsen-b.com/Article/290.html) (benchmark of
2d performance between ATI and NVIDIA on Linux).
I hope I helped some of you and hopefully I saved you a lot of time and
frustration…
Cheers,
Dejan
