Hi i have experienced a very nice boost after upgrading my game to Unity 5.0.0b9 but after i upgraded to b13 today the framerate is now dropped by 50% (in b9 my framerate was 120-125fps but in b13 it is now only 60-65fps!) how come that be??? it was all planned nicely for the PSM version but now it probably won’t be faster than using 4.3.7 
any kind of info on Unity boosting the engine back up will be highly appreciated!
Thanks,
~David
Send bug report.
yeah, i would do that but i cannot explain how to reproduce it…
and i may be wrong (please tell me if i am 
) but i have always thought that i was required to tel how to reproduce anything that is being submitted to Unity Bug Report???
If you’re saying that in 5.0 b9 your game was twice as faster than 5.0 b13, then you’ll need to submit a bug report with repro project attached, and say that you see a performance regression between 5.0b9 and 5.0b13
@Tomas1856 - yeah that was what i saw… but now that i have returned to b9 i can only see up to 63fps so maybe it was just a mistake??? because I can still see over 200fps in speed on the stats tab! the 60-63 fps was on an free fps counter! so maybe the counter was making a mistake? anyway i cannot reproduce it which is annoying but not much to do about it… But thanks anyway guys, i appreciate your tips and help 
You’re sure you didn’t enable Vsync in the quality settings?
Hi there, nope Vsync WAS on but i have now turned it off to see if that changed anything and it didn’t!
Like i mentioned to Tomas, i think it is due to the free unity asset i use called FPS Counter! i think it may not be 100% accurate in Unity5?! it is however just a hunch
Have you also tried restarting Unity?
Vsync in the Editor tends to act a little wonky in my experience, but restarts seem to help. Maybe that’s just me.
Yup just did that, and i could get a boost for a short moment up to 70 fps… i have also wondered if it can have anything to do with me using an 60Hz screen??? or would that only be the case if i still had Vsync turned on??
You can’t really use the FPS counter to measure framerate above the targetframerate or refresh rate, as it only measures the frequency that Update is called, use the profiler to measure performance, I’d imagine the difference you are seeing is either you was remembering the stats, or you’ve updated you graphics card driver or something.
well, i did see it on the fps counter (a free asset on Unity’s Asset Store) but it may have been something to do with my computer somehow… anyway it still says over 200fps on the stats window so i think that is quite promising though it may could have been higher? no matter what then i am satisfied with it 
I don’t really want to keep on looking for a solution to something that may have been a mistake from an asset in the first part no matter what, thank you guys for trying to help me out, and i just want to point out it isn’t Unity that has changed anything it must be my computer somehow (maybe some driver(s) like Jonny Roy mentioned!?)
There was a lot of lighting changes and stuff that auto reset or changed when i went to beta 13. One thing that was pretty big was it caused many of my lights set to “not important” to change to “important”. That would cause a pretty big slowdown. I also noticed my ambient light intensity changed too. This may not explain everything but it’s a start.
