Your graphics card is probably too new to be recognized. It may be recognized by a more recent viewer such as the Firestorm 4.7.1 release. The problem is the list of cards found in the viewer installation: gpu_table.txt You likely need an updated version (you can copy one from another viewer, such as Firestorm or even SL) or the graphics are so new that it's not known to the updated file either.
It's either an Intel Iris or an ATI R9 card...... if you find that Jim's solution doesn't work (The card may in fact be too new) post here and I will make you a custom gpu_table.txt that will fix it.
