The new version includes project files for PTGui and Autopano with comparable output size and format, so you can directly compare performance of both stitchers.
Please note that PTGui will perform much better in the new version. The main reason for this speedup is, that i have used the "crop" feature available in newer releases of PTGui. This complies with Autopano which will cut unnecessary image parts automatically.
To give you some figures, i have re-rendered the panorama with the new project on my reference system - meanwhile upgraded from Vista 32bit to Windows 7 64 bit:
- old project on old system:
2h, 38min - old project on updated system:
1h, 24min (speed increase 1.88 - just by using 64bit!) - new project on updated system:
57 minutes (speed increase 2,77 compared to old numbers!)
