perform mode fps low problem with kantan mapper

Hi all,

I met a performance problem. I used a KantanMapper for projection mapping in my td file.
If I clicked ‘toggle output’ in KantanMapper, the fps of the output window is around 30 which is acceptable and nearly the same as shown in td when no output window.
But when I open the td directly in a perform window in which the window operator is the out1 from kantan mapper comp, the fps drops to 15.

The setting of the perform window is the same as the setting in kantan mapper.
I have no idea why there is a difference on the performance.

Anyone has idea?
