hello, on Linux, you can change vertical syncro that using nvidia-settings tools if you use a nvidia GPU. Otherwise, i don't know, certainly tweking the Xorg.conf. (look for"sync to Vblank")
Using triple buffer may provide solution for faster than screen rendering, but i don't see the point in that. If you have a shader or somthing else that sould be faster than sreen rendering, you still can bang gemhead with a metro... cheers cyrille Le 30/05/2012 21:22, chris clepper a écrit :
GEM is set to VBL sync based on your monitor's refresh rate. I vaguely recall putting some sort of message about turning this on and off in the gemwin. With it off you will often see horrible tearing artifacts on the display, which is why it defaults to 'on' on OSX (and apparently Linux too).

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. -- William Brent www.williambrent.com <http://www.williambrent.com> “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com <http://www.conflations.com> _______________________________________________ [email protected] <mailto:[email protected]> mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
