Hi Jeremy and Noel, thank you for your reply. I've been following your advice and here's how it went: 1. in OpenGL things get even more dramatic, here's a picture: 2. the latest driver was installed when I first used 3d extruded polygons and realized there was a problem. 3. yes, I had a problem in other machine with other 3d software that wasn't working with the latest driver so that makes sense to me. I've tried all the versions of the Firepro driver for v5800 available for download in AMD's site and also a version that Windows Update installs, a total of 4. I always cleaned up the previously installed drivers before installing a new one and currently I'm running the latest again. I noticed that the Direct3d version of the drivers is always the same, don't know if that has any relevance. I have no issues with any other 3d software that I use. Don't know what else to do. I have an ArcGIS license for personal use so I'll try to contact support and I'll also try the AMD support. Is there any other settings I can try to change to pin down the problem? Thanks in advance.
