Vsync prevents using fresh motion capture data in physics simulations?

[farshizzo]

Having the physics simulation run asynchronously from the main loop is not currently supported.

If you don't mind the tearing, you can disable vsync to have the main loop run as fast as possible:

viz.vsync(0)

If you would like to disable vsync, but still set a limit on the frame rate, you can use the viz.max_frame_rate option:

#Set max framerate to 120
viz.setOption('viz.max_frame_rate',120)

Thank you for the reply farshizzo. Unfortunately, the answer is a bit disappointing. The NVIS line of helmets requires a 60 hz input, and will not function if vsync is turned off, or >60hz. I study human visual-motor behavior, and cannot allow visual tearing in the stimulus.

Until this issue is addressed, accurate real-time immersive interaction is not possible. This is a huge impediment to my own research. I will workaround this issue for as long as I can, but forsee having to switch away from Vizard if this is not eventually addressed.

Please keep me updated!

Thanks again.
