I have a simple patch i put together for shits 'n giggles.

qmetro 20>jit.noise 4 char 320 240>jit.matrix>pwindow

as a locked patcher, it is somewhere ~45 fps

in presentation mode (with the pwindow scaled up), it drops to around 30fps.

is there always going to be that big of a performance hit when using

are previous performance tweaks, like eliminating updating gui

components and other fun optimizations, now obsolete?

secondary question, is it possible (or will it be so in the future) to

change attributes, separately for presentation mode?

secondary question, is it possible (or will it be so in the future) to
change attributes, separately for presentation mode?

The performance hit is not related to the use of presentation mode, 

just to the fact that the jit.pwindow is bigger, and it's performing 

some scaling operation in order to display the incoming matrix into a 

different object size. If you specify the same size, you get the same

The performance hit is not related to the use of presentation mode,  
just to the fact that the jit.pwindow is bigger, and it's performing  
some scaling operation in order to display the incoming matrix into a  
different object size. If you specify the same size, you get the same  
performances.

Best bet in general is probably to also use jit.pwindow in the 

presentation mode size in both edit and presentation settings.
