Hi,
I have similar problems with an ATI Radeon HD 5850 in Windows 7 64bit.
Textures are corrupted, it seems like the MIP levels are mixed together
somehow, so that different textures are shown and blended together
depending on the viewing distance and angle. I have tried different
versions of the Catalyst drivers but to no avail. The phenomenon doesn't
appear with all models but it feels like it's an ATI driver issue
anyway, triggered by something special in the failing models, but I
haven't figured out what just yet.
Does anyone else have the same problem or know how to solve it?
Regards,
Andreas

I would have to disagree and say that it is likely to be a hardware\driver
issue
I have been running OSG on 64 with Nvidia for 3 years and had no issues
There have bee quite a few posts recently about continued issues with ATI
catalyst drivers and their broken Opengl Support, the suggestions from the
post is to use catalyst 10.4 drivers

Subject: [osg-users] Texture problem on 64-bit PC
Hi,
I recently received a new 64-bit machine at work. When I now use osgviewer
to the textures on some of our models seem smeared where they displayed
correctly on my older 32-bit PC.
Other models do display correctly, so I don't think it's a hardware issue.
Our models are in the form of IVE files, and some of them are generated by
(an older version of) Virtual Planet Builder.
For what it's worth, my PC runs Fedora 12 and has an ATI Radeon HD 3450
graphics card. I also had Fedora 12 on my previous PC, but it had a NVidia
card.
I would post an image, but I'm a newbie, so I'm not allowed to post URLs
Has anyone had similar problems? what causes it? How can I resolve it or fix
the models?
Thank you!
