Hi to all.
Just an update.
I set the isolcpu=1.
I disabled the legacy USB support from the BIOS .
I finally remove the Nvidia drivers + the NOUVEAU drivers and reboot the
system.
After that the latency numbers are pretty good (I mean comparing with the
previous numbers) .
The base thread peak is le
Thank you Kirk for your detailed explanation I will try your tips.
My cpu is an Intel dual core so isolcpu=1 should be the right one .

How many cores? If two, the isolcpus=1 is correct; if four, or one or...
it may not be.
I modified Kent's "07_rtai" script to find the pae kernels; some

Thank you Eric.
Your observation may be correct .
The Nvidia driver installation is a big issue for many users that are not
using LCNC .
I will remove the drivers I've installed and I will go for the Vesa
solution.
The Gigabyte and ASRock mobo seems to be better than ASUS for LCNC.
And to have a se
Vesa worked fine. The open source Nvidia drivers were not good for
latency. You may wish to go with an interface that doesn't use 3d. I
believe that the problem with the Nvidia system is that they want a
specific kernel layout and it doesn't work with the RTAI kernel, but I
can't be sure

Hi Eric .
Did you get good latency numbers with Vesa drivers.
My need is to get the best latency numbers is possible.
If it's better to use the Vesa drivers I will do that .
Nowadays the two biggest Graphic cards/chips manufacturers seems to be
Nvidia and ATI so why it is so hard to get this cards
Last time I set up a lcnc system I had a lot of trouble with the Nvidia
drivers -- they wouldn't install. I did go with Vesa. I don't really
think it's a problem.

Hi Dave .
Actually seems that the NOUVEAU drivers are used as I can see into the
Xorg.0.log file I've attached .
Do you suggest to use the Vesa instead of Nouveau ?

Nvidia is a known problem see

try those solutions and any other graphics card you have lying around

Hi to all.
I've built a new desktop pc (honestly I bought the hw components a couple
of years ago) to use it for LCNC application hoping to get a good latency
numbers .
The mother board is an ASUS P5KPL SE ;
The Graphic Card is an ASUS EN8400GS 512MB based on the GeForce 8400GS chip
;
The Processor
