    Hi,

    I made a completely empty new scene with no scripts attached or anything, and it is spiking on the profiler at 4.6ms regularly with garbage collector. This isn't happening in 3.42. What is the problem?

    noticed a similar result on osx 10.6.8.
    and if i update a project to 3.5, vsync is enabled which snacks about 60% of the performance in playmode.
    the other new features are great fun to test and seem to work, thanks!

    It's the profiler itself that is causing the GC spikes. Unity are not doing any caching with string pools for the profiler so what you are seeing is the GC collection stats for all of the string labels in the profiler :(

    UT pan to address this at *some stage* in the future.

    Ah, harmless then. Thanks! Didn't notice it in 3.42 though, or maybe it's my imagination.
