<![CDATA[CPU load with Purr-Data and GEM]]>Hi there,

I started dealing with GEM and implemented a very simple patch that simply plays back a video. When I run this patch with pd-gem the playback is all good. But with purr-data the playback stutters since the CPU load is too high. Please find attached screenshots of the patch and atop while running the patch with purr-data and pd-gem.

The pd version with purr-data and pd-gem is slightly different, but I assume that this is not the root cause. So, what is the problem with purr-data and how can I solve it?

Thank you in advance!
Andre

Are you observing a similar behavior? I assume that this issue systematic, i.e. caused by the different way Purr Data puts data onto the GUI since it is based on HTML5 in contrast to Vanilla PD.
