fps drop from 80 to 20 after reimporting project

Hi,
I've been both windows and Linux user at the same time,
I've been using unity on windows only
then, I decided to move to Linux permanently, I was workling on a game so i saved the project folder and imported it to Linux, after installing 5.6.1xf1Linux Unity Editor everything worked fine i just dropped the project from windows, in my new unity projects folder. the problem is that on windows i used to get 70 80 fps but here I'm getting 20 27 ... how do I fix this?
and do you recommend that i just develop on unity on windows? and forget about Linux?
i'm on UBUNTU 16.04
I have
an APU A8-5600K
an NVIDIA GT740 2GB 128-bit
ADATA GOLD 8GB RAM
1TB SEAGATE HDD
1TB TOSHIBA HDD
160GB TOSHIBA HDD (OS)

I'm using Nvidia's 375.39 official Linux Tested driver

 

anybody ? some help please ?

 

Hard to tell.

A guess: check whether your 'Console' window fills up with messages. Those can drain performance like crazy if they're generated at one or more per update (which may happen if, for example, some script tries to access a reference that broke during reimport).

Otherwise, likely the only thing you can do is to disable everything in the scene and enable it piece by piece until the frame rate drops to figure out what's causing it. If it's Unity itself (= empty scene has 20 fps), it may be a good repro case to send to Unity support

 

i did that and every time i remove something the fps goes up
but that shouldn't happen it should have the same fps it had on Windows

 

I am having the same problem with FPS, and will make a post with detailed comparision between windows and linux editors in my game. I will also link the test project so everyone can test how it performs on their system. I really hope this will get fixed. But no time yet

However, i noticed that you use 740M. It's a mobile card often working together with builtin video. In that case, did you install bumblebee and switched to 740M? Because if not, the default is usually builtin, and it's very slow. Unlike windows, where you select video card for every app you run, in ubuntu in many drivers you select it, and re-login, making everything run either on 740m OR builtin, including unity.
For example, look for the label on unity-editor window. If it says anything lower than openGL 4.5 (like OpenGL 3.2) you're probably on builtin video.
I am not sure if it's relevant to your notebook, but decided to share

no i don't have a laptop .. it's an Asus Nvidia GT 740 .. not 740M ..

 

All of the above is probably not drains in performance, but 3 at least parties writing to the buffer like it is international poker.
Mind looking or showing the xorg file?

 

i'm no longer on Linux i went back to windows just to continue developing
