Hello list, I do not know if this topic goes here, but comment as well.
I installed ubuntu 10.04 (I updated the packages) and the new version of pd (0.42.5) on a computer intel core 2 duo, 4 gb ram and processor 2.4, nvidia G210 card (256 ram), library PiDiP and Gem went very slowly using a webcam ISLIM Genius compatible with Linux, Win, and Mac, Also i installed in an intel atom hp mini 1000 (intel atom processor), on a celeron with 1 gb and a mac osx 10.6, and had no problems, but Lucid latency was terrible, I tried uninstalling the NVIDIA card and still the same, I went to ubuntu 9.04 (without the card) and it worked perfect ...Why? I dont know...
Best regards
José

THanks Markus, Yes, I have checked the conditions and I fully understand the theme of light. In relation to the priority of camera do it from the same patch (I have only a webcam) conformed dimensions and metro, but nothing happened, you could tell me how to give priority to the camera before running pd?
Thanks again Markus

The priority i was speaking of, is for the camera internals only...
What does the output of glxinfo tell you? Did you try luvcview?
