ArcScene 10.1 Orthophoto Visualization Issue

I am attempting to visualize an orthophoto in ArcScene 10.1 at the same resolution it is at in ArcDesktop 10.1. I have set the "Quality enhancement for raster images" to it's highest extent. But, the resolution is still low (i.e. it is very pixelated). In ArcDesktop I can see individual downed trees within the orthophoto, but within ArcScene I can barely see roads. Does anyone have any suggestions?

Thanks in advance.
