I use the Firestorm viewer for Second Life and it is very good. I have been using it for over a year and just upgraded to the latest release. Yesterday had what I thought was a disaster. I couldn’t see mesh the 3D modelling of objects. There were just gaps where clothes would be. I thought my graphics card had broken, and it had. I had just updated the drivers. However I didn’t know this and I asked friends what to do. They took me through various settings nothing worked. Then it was suggested I ask the FS Support group in chat. I joined the group and typed my problem into chat. Almost immediately the answer came that I had to roll back my drivers to an earlier release. It was the new AMD drivers that were doing it. So I did a system restore. Everything went back to 4th December. And everything worked.
So my Firestorm does not support certain builds of AMD drivers. I went back to release 13, 14 seems to have problems in its various forms. Finding this out took a matter of seconds. What a great resource to have that Chat. Excellent stuff. I watched it yesterday and picked up some tips. It seems no problem is too small to help, from fiddling with a graphics setting to a complete install. Well done Firestorm. They also have a wiki and JIRA and forums. http://firestormviewer.org
