    hello,
      
      
      i'm using a gem patch inside a pd~, in order to separate a huge
      computation, and the rendering of this process. But since i need
      pix_image/pix_data in the 1st process, i have to open 2 gem
      windows. only the 2nd one is visible.
      
      
      i'm using export __GL_SYNC_DISPLAY_DEVICE=CRT-0 do have vsync on
      the external screen. (don't understand why nvidia-setting did not
      work any more for this)
      
      
      my problem is that only the 1 gem windows is sync to Vblank. but i
      need the 2nd to be synchronize.
      
      
      i could modify all my patch in order to have the rendering in the
      main pd patch and computation in pd~, but that would be a huge
      work.
      
      
      So i'm looking for a way to force sync to Vblank for all openGL
      windows. (nvidia setting use to work for this, but did not
      anymore).
      
      
      
    
    hi!
    
    driconf has settings for vblank too. possibly its config file .drirc
    already exists on your system, overriding any driver settings...?
    Just guessing.
