If the dissolves of high-resolution images are jerky instead of smooth and fluent, this may be due to the following reasons:
You are using an unsuitable graphics card with insufficient graphics memory.
There chosen hardware rendering mode is not appropriate.
In relation to the available graphics memory the texture file you have chosen is too large.
Your show is very complex and uses a high number of simultaneously visible pictures and videos, which cannot entirely be accommodated in the graphics memory.
Solutions:
Optimize the display data (also called textures) to adjust them to their corresponding usage in the timeline. See Optimizing display data for pictures.
The log file logs the locations in the show where media could not be loaded properly into the graphics memory. See Displaying log information.
Select a smaller size for the display data, e.g. 1024 pixels width or smaller. This has a negative effect on the resolution but playback should be smooth again. See Screen Properties.
If you are using two monitors you could change over to single monitor mode. This provides for a higher graphics memory for the texture files.
If the problem only comes up for more complex sequences, it may suffice to reduce the texture size of individual pictures. See Changing the display data quality for individual pictures.
Moving image contents are particularly critical. Loading of textures while a picture object is moving on the screen may easily cause the movements to be jerky. This depends on the texture size and the computer performance. If you want to specify a central folder for storing the picture display data – which however, should definitely be on the fasted drive – go to Options – Global Options - Save.
