Hello Anita,

Are you referring to print statement such as this one?

        PF Notice: Using 60Hz video rate.

If it's the case, it's easy to catch up these printfs using pfNotifyHandler().

#include <Performer/pr.h>

void notifyHandler(pfNotifyData* data)
{
   if (data->severity <= pfGetNotifyLevel())
     send data->emsg to your GUI;
}

void main()
{
   ...
   pfNotifyHandler(notifyHandler);
   ...
}

See pfNotify(3pf) for the complete man page.
