    I was Deep Profiling "Enter PlayMode" using the built-in Profiler from Unity 2019.4.20f1. I then tried to save the capture, but the tool didn't let me and decided displayed the error instead:
    Unable to save profiler frame 54 to file "test.data": frame size is larger than 2GB

    Hi Peter,
    We are aware of this limitation. The log message was added as surpassing the 2GB threshold previously just crashed, as the .data format is inadequate to deal with frames this big, so now they are dropped (Obv. not an ideal solution). Also see this other recent thread:
