different timings on quad and dual core machines RRS feed

  • Question

  •  I'm getting very different frame times from a dual core and a quad core computer running the same code. I am using the polling method of getting frames.

    Is this normal? Is there a way to get the driver to act the same on both types of machines?

    The columns are frame number, ms time, ms since previous frame. These timings are from the depth frame.

  • We've done work on frame timing and syncronization between different streams in v1.5.

    Could you try with that new version and report what you see?

  • With the new version, I no longer see the difference between the machines. Thanks!
