Hello Burlen,
Thank you for this information.
Indeed, my laptop is very old: it is a Toshiba Satellite X 200 with
Vista 32 bits that I purchased in 2007. The NVIDIA driver has been
automatically updated by Windows update to the 7.15.11.7626 version in
2008 or 2009, I don't remember. The most recent Vista 32 bits driver
that Toshiba gives on its download page for this laptop is only the
7.15.11.7605 version that is older than the version I got from Windows
update!
I have downloaded the 307.83 version on the NVIDIA download page, and my
card is in the list of compatible cards. I hope it's true! I will try to
update my driver this evening.
Thanks again.
Richard

Hi Richard,
Your video card is fairly old and it doesn't support the extensions
used by the new version.
The 2.0 Surface LIC in PV 4.1 is a true parallel implementation and
has additional requirements compared with the original serial code.
However, there are no exotic requirements, all have been adopted into
the OpenGL standard many years ago. So most recent hardware/drivers
will provide the required extensions.
NVIDIA's spec
sheet(http://developer.download.nvidia.com/opengl/specs/g80specs.pdf)
doesn't show support for GL_ARB_depth_buffer_float. Based on the info
you provided that's my best guess as to what's wrong. However, I found
a mention( http://en.wikipedia.org/wiki/GeForce_8_Series) that the new
drivers for the 8 series support OpenGL 3.3, which includes floating
point depth buffer. Updating your driver may resolve the issue.
