Hi list,
I'm trying to get the fastest possible frame rate from GEM, and seem to be hitting a limit of 60fps. Is this a known limit? I searched the documentation and pd-list archives, but maybe I'm missing something. The final application I'm working on is video tracking, but here's a test patch with nothing more than a gemwin and a counter incremented by the gemhead. With a frame rate of 90 for the gemwin, it takes exactly 3 seconds to get the counter up to 180, when it should only take 2 seconds. At a frame rate of 60, it takes the expected 2 seconds to get the counter to 120.
I'm running this with Pd-0.43-2 and GEM 0.93.3 on Ubuntu 12.04 using the -noaudio flag. I get the same results on Mac OS 10.6.8.
