Hi, while working on Panotour 2 I noticed it is consuming a lot of memory, you can imagine it was consuming 4.3 G.B from RAM while building virtual tour ( 62 images ) ... I wonder is that expected behavior.
Yes it is the expected behaviour.
When you launch Panotour, it looks for the available memory at this time, and it takes a percentage of this memory, to ensure to be able to work on big tours or big panoramas.
You can parameter the percentage it takes in the Preferences window of Panotour.
