<div class="moz-cite-prefix">Hello Burlen,<br>
<br>
Thank you for this information.<br>
<br>
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!<br>
<br>
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.<br>
<br>
Thanks again.<br>
<br>

Hi Richard,<br>
<br>
Your video card is fairly old and it doesn't support the
extensions used by the new version.<br>
<br>
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.<br>
<br>
NVIDIA's spec sheet(<a moz-do-not-send="true"
href="http://developer.download.nvidia.com/opengl/specs/g80specs.pdf">http://developer.download.nvidia.com/opengl/specs/g80specs.pdf</a>)
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(
<meta http-equiv="content-type" content="text/html;

<a moz-do-not-send="true"
href="http://en.wikipedia.org/wiki/GeForce_8_Series">http://en.wikipedia.org/wiki/GeForce_8_Series</a>)
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.<br>
