    Hey All,

    I have a simple project that schedules and times a large number of RaycastCommands against a giant terrain collider for benchmarking.

    When updating to 2018.3 beta, I was expecting to see a ~2x performance increase but instead I am seeing a performance regression of about ~40%.

    For example, it took 175ms on my machine for Unity 2018.2 and then 250ms on my machine for Unity 2018.3b

    Hi Bryan,

    Let me say that's totally not expected to see raycasts slower in 18.3. Like others said, please do send out your test project and we'll investigate. Thanks!

    Hmm sorry for the alarm!

    I made another project from scratch and it looks like I am seeing the faster queries now.. There was something strange going on with the initial one I was using.
