Molecules look poor on Windows 7 (versus XP)

Hi all,

Since I’ve ‘upgraded’ to Windows 7 (64-bit), I’ve noticed that the
quality of rendering in Avogadro has gone down. I used to use Windows
XP (on the same machine, but 32-bit) and as far as I remember it all
looked pretty good. The machine itself is my desktop powerhouse, but
is probably using onboard graphics (if you need more info, I can look
into it).

I’ve posted the current image on friendfeed at
http://friendfeed.com/baoilleach/e055b2c0/poorer-quality-molecules-with-avogadro-on.
And this is with the quality turned up to the max. (That’s phenol, by
the way)

I this in VMWare? Do other OpenGL apps work? Do you have a recent
graphics card driver installed (even if it is some onboard chip)?

I get the same results when I run Avogadro in VMWare win XP with
software rendering.

Yes, we have seen this before in VMWare. Ideally I wanted to remove the use of
what does not seem to be a very widely used part of OpenGL (the way we
generate the normals each frame for spheres). It would be good to know what
driver, card etc you are using.

This is on bare metal (i.e. not virtual). PyMOL works. The onboard
chip is Intel(R) Q35 Express Chipset Family (Microsoft Corporation -
WDDM 1.0) and is driver version 8.15.10.1749 dated 06/05/2009.

I’ve just updated it (to Sept 2009), but it requires a restart and I’m
in the middle of running something, so I’ll see if this changes
anything tomorrow morning.

After updating the driver, it now works perfectly. I know, I know - I
should have done that first :slight_smile:

For future reference, to update the driver I went to Control
Panel/Display/Change Display Settings/Advanced Settings/Properties (on
Adapter tab)/Update Driver (on Driver tab). Windows found the driver
automatically on the web. The driver is 8.15.10.1930 dated 23/09/2009.

I downloaded and ran GPU CAPS viewer just to see what it would say,
and on the OpenGL tab it has OpenGL version 1.4.0, but says it does
not have any GLSL capabilities. So it seems that it may make sense to
shell out in future for a graphics card. I thought that without a
fancy graphics card it would just run slower; instead it seems that
there are fewer features.
