I honestly haven't had many probs with the 2.2 ver upgrade! It hasn't crashed on me yet. I have imported some terrain and set pieces into it from Wings and it handled them without a prob. Painting and exporting displacement maps and textures works fine for this use but there are still some problems with map seams occassionally. I would probably have to finish up the maps in PS3(I don't have it, but my friend does) to have critically flawless maps for boned and rigged characters.
