    I'm in a very early stage of development, when playing the game in the editor it runs at ~700 fps, when turning Maximize On Play in the editor the fps drops to 16. That's twice the amount of pixels and 2% of performance.
    There are no dynamic lights or screen space effects. What am I missing?
    Thanks!

    Either test a player build and not in editor or open the profiler to see what is using your CPU time. I guess it's the editor loop for some reason.

    Forgot to mention that I've tested a build and got the same slowdown. The profiler doesn't tell me much, maybe I'm not reading it correctly?

    This is probably related to some kind of post processing effect you're using?

    I know i had a problem with SSAO before i toned it down.

    Well, the problem solved itself, no idea how. Probably it was not related to unity...
    Thanks for the help!
