My system is oldish (five and a half years) HP Envy TS15 with i7-4700 MQ at 2.4 GHz; NVIDIA GeForce GT 720M.
Windows 10 Home v 1809
Took a project of 28 main slides (two of which are video clips, 12 sec and 21 sec long) with 8 other slides inserted as picture in picture.
Transitions are of different lengths, but all straight crossfades from one to another.
Very smooth and quicker, thank you:
