Problem: very unstable FPS (70...700) Why?

Unity Engine
1

Hello.

I have a problem as in the title. Unity 4.6.5 Personal Edition.
I have a 3D project. 50 - 100 3D objects moving on screen.
And in several subsequent runs in the Unity editor, FPS is 60-70 and once again… 600-700.

Rendering time remains unchanged (2-4 ms) but changes the total time. From 1 to 15 ms.
Also changes the behavior of physics.

NO CHANGE IN THE PROJECT: 70FPS time, once 600FPS. (approximately) No intermediate states.
These same objects and screen. Without significant changes to the view …

Error in Unity or something I’m doing wrong? Someone had such a problem?

I know you do not give me one solution to the problem, but how to look for solutions?

Regards,
Kajetan

Use the Profiler and see what is spiking.

Exactly … there is a probem :frowning:
I used profiler directly into Visual Studio …
I can not run it in Unity. Does the non-Pro version does it work?

Why can’t you run it in Unity?

I do not know well Unity.
I’m writing a game for the PC. In the description of the use of the profiler, I read
is that you have to switch the Windows Store, but in tymśrodowisku
I play does not compile.

Do you have a link that describes well not the profiler (I know how it works), but
the way its launch in Unity?

All in all, everything works fine when running a game in Unity environment.
But when I started tests on the tablet and the PC, as he noticed that physics
changes speed. I began to check and noticed the problem with varying frame rate.

Sorry can’t help you as there’s so little information, or I don’t understand you.

Instruction: “You can play your game in the Editor with Profiling on, and…”

WHERE is “Profiling on” … I can not find this… I do not see anywhere this option? :frowning: :frowning: :frowning: :frowning:

Window->Profiler. It’s in the manual.

Well, we’re back to the beginning … I read the instructions …
I was lookingthis for the last half a day, and I have no option “profiler”.
Is this option Unity 4.6.5 PERSONAL EDITION, if only in the Pro?

I could ask for a screenshot? …

Its free in 5.0 Personal edition.

Ok, thanks. Now there will be another question.
“Why do some shaders do not work in 5.0” …
But this in another thread. :slight_smile:
