Hi, I tried to puzzle this together from my (vague) memory of the IRC discussion with Ian about this topic and my own thoughts. Here is the result:
Synchronization with vertical refresh (swap intervals): - Never, FPS rulez! - Application preference, default interval 0 - Application preference, default interval 1 - Application preference, always synchronize with refresh The thing I'm not sure about is where to set the default swap_interval. I found that the environment variable LIBGL_THROTTLE_REFRESH is still used in xc/lib/GL/dri/dri_util.c (driCreateDrawable) for this purpose. As driCreateDrawable does not have a current context there is no way to access the XML (per-context) configuration from there. I believe the driver's makeCurrent function is the only sensible place to set the default swap_interval. If it was initialized to some special value by driCreateDrawable then the driver could set the configured default value there. We could add a new function in the driver-independent code for that. Thoughts? Best regards, Felix P.S.: I kept answering my own questions while I was typing and ended up with a plan. :) Is it a good one? ------------ __\|/__ ___ ___ ------------------------- Felix ___\_e -_/___/ __\___/ __\_____ You can do anything, Kühling (_____\Ä/____/ /_____/ /________) just not everything [EMAIL PROTECTED] \___/ \___/ U at the same time. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
