Hi Julian,
I'm cc'ing the psychtoolbox, in case anyone else is also curious about
this. We are using the dots regularly on at least one of our monkey
rigs and periodically for human psychophysics (maybe more, I haven't
asked all of the researchers) and haven't had any problems. It does
still take a second or two for the dots to initially load, but after
that you can run for hours and hours without any dropped frames,
regardless of the size of the dots or aperture.
cheers,
maria
