Giving possibility to turn v-Sync off in MadMapper

Postby krokoO » Sun Nov 27, 2016 1:36 am

Hello,

Would it be possible for MadMapper to have a user preference, where one could turn v-sync off.
Currently it is not possible to run an app faster than display Hz if that app publishes data via Syphon Server, and there is a client, that listens to the Server and has V-sync on.
By being possible to turn v-sync off in MadMapper (which is working as Syphon Client), user could run application (that exports Syphon) at desired frame rate (above display Hz).

Related thread: https://github.com/Syphon/Syphon-Framework/issues/36

Thanks!

In the mentioned thread in Github I added a test, that shows that indeed, if Client has v-sync off, then the app that is used as Server can do more calculations per second while still sending data to Client.

Ok. It will be possible in 2.6. If you want a pre-version, send me a PM.

You'll have to enter that in Terminal:
defaults write com.garagecube.MadMapper doubleBufferredPreview 0
defaults write com.garagecube.MadMapper doubleBufferredOutput 0

When a Syphon input is used, MadMapper will try to render as soon as we receive a "newFrameHandler" notification from any Syphon server used (since we can use multiple Syphon streams at the same time). So it should be clean.
Can you send a QC patch publishing a Syphon at high FPS ?
