Hi Fabrice, so the trial version is wrapped with this mechanism called WinLicense which makes it more difficult to be modified to have the time limit removed.

It could be possible that is the source of the performance difference. The V3 30-day trial also has it but it's an older version and maybe I need some adjustments to the newer V4 one to avoid too much performance penalties.

Can you please send me an e-mail at moi@moi3d.com and I will prepare a different kind of v4 trial for you with no WinLicense wrapper but instead with saving disabled. If that behaves better then it would confirm that as the area that I should focus on.

The full release version does not have the WinLicense wrapper on it.

Thanks,
- Michael
