does running internal profiler slow down framerate?

I’m trying to get an accurate read of how many FPS I am actually running, but when profiling my app it really appears to drop it’s framerate when running the internal profiler which is connected to adb via wifi. I have never seen this mentioned but it this to be expected? Is there a better way to get an accurate read of fps?

Yes, running the profiler will cost you some extra performance and memory. You can add a simple FPS counter to the project, if that’s all you are concerned about.

Calculating the framerate is quite simple, so you could do it yourself. But there are some free scripts readily available that can help: http://wiki.unity3d.com/wiki/index.php?title=FramesPerSecond

There are some nice counters on the asset store as well: “fps counter”, “framerate”
