Hello and thanks for the quick reply. We just tested your solutions and they seem to help a little bit on the Mac (less jerks), but not at all on the PC. How do you think we could improve it ? TIA.

Hi all ! We are a small french team, trying to create a virtual tour that won't be read online but stored locally. So don't worry about the black screens during loading times. We meet rotation issues in our cubic pano : fuzzy waves and jerks. We looked for solutions on these boards and applied all of the ones we found : Flash 10 ON, increasing move and still quality to highsharp, increasing details to the max, slowing down camera movement etc. Nothing does the trick, impossible to eliminate this...
