Hi guys,
Just a progress report, some encouraging news.
I've been discussing with nvidia dev support on these issues since
Friday. They have really been responsive and quick, and they are
thorough in their investigations too (I guess I was lucky because the
guy replying had the same model
J-S,
Thanks for the update.
Since Optimus is currently Windows-only anyways I think that's the
path they'll choose.
Just as an extra point, Ironhide lets you use Optimus under Linux. I
haven't done any performance testing, but I was able to to manually

Hi all,
We have recently bought a few good laptops (Lenovo W520) to be able to
work at customers' sites, and these come equipped with Intel graphics
AND an nVidia Quadro 2000M discrete card. They are supposed to use
(buzzword alert) nVidia's Optimus technology to automatically switch

Replying to myself,
I haven't tested other OpenGL apps. I will soon.
I just tried Lightsmark 2008 [http://dee.cz/lightsmark/] and it wouldn't
start, saying in its log file that Graphics card driver doesn't support
OpenGL 2.0. So I guess that's the same result as our OSG app I tried
before.

Hi Martins,
Just this morning I started testing on one of these laptops (Dell
XPS17). By adding a profile for the specific .exe I wanted to run, I got
the Nvidia graphics to kick in for our OSG application. I have not yet
found a way for that card to start automatically with OpenGL apps.
J-S,
Which version of the drivers are you using?
I'm using 268.30, the most recent as provided by Dell specifically for
my laptop. I have not tried any of the drivers on Nvidia's site.
I'm using 280.26 from nVidia's site, and even creating a profile and
setting that profile to run on
Hi Martins,

Well, I just reverted to the 268.71 version that is provided by Lenovo.
On this version, selecting the discrete graphics in the Global Settings

Reason number 1 why I have quit buying Dell.
