Windows 10 performance decrease

When you upgraded to Windows 10, did you perform a clean installation of the latest Windows 10 compatible graphics drivers?

I use GeForce experience, and installed the most recent driver for my GTX860m.  Currently if I go on to GeForce experience it tells me that I have the most recent driver.

Do what Fred_vdp said.

You can use Driver Display Uninstaller (DDU) to remove any previous driver files from your pc http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

and then download from nvidia windows 10 compatible gpu drivers and install.

Or select advanced installation from nvidia driver and check box "clean install".

Yes, definitely use DDU to make sure all traces of previous drivers are gone.

Geforce experience produces negative results frequently with DICE's Frostbite engine-based games.  Avoid it. 

I use a Lenovo Y50-70 with the following specs:

OS: Win 10 (Build 10586)

CPU: i7-4710HQ @ 2.5GHz

RAM: 8GB

GPU: GeForce GTX860M w/ 2GB GDDR5

HDD: 500GB

With that aside:

Before upgrading to Windows 10, I could consistently get about 40FPS (not to mention it felt buttery smooth) playing on High.  Now that I've upgraded to windows 10, I'm barely pulling 30FPS, but the difference is VERY noticeable: watching the AT-STs and AT-ATs move looks like stop motion, the Hero/Villain cutscenes are choppy as heck, and flying is almost impossible.  

Worth pointing out that every other game on my computer runs perfectly fine with the exception (of course) of Battlefront.

I was reading through some suggestions on this thread and saw the idea to check to see if my Intel 4600 graphics driver needed updating.  Sure enough, it did.  I restarted my computer and launched Battlefront and it played perfectly.  I closed it for a couple of hours and then played it again and now it's back to the crappy 28-30FPS performance.

Let me knock these ideas off your checklist before you suggest them:

-GTX860M driver is up to date

-played with nothing open on my computer but Battlefront

-restarted the game and my computer multiple times

-turning graphics down to "low" doesn't help

-disabling my Intel driver when I launch the game gives me this message

-Battlefront is using the 860M and not the Intel 4600 

As everything else works perfectly fine on my computer, I refuse to revert back to 8.1 just because this game does not work like it should.  

I have tried all of the above suggestions and uninstalled GeForce experience and I am still barely getting (very choppy) 30FPS.

@butchthedoggy, did you tried changing energy profile? Try performance profile. Try also disabling Origin in game (overlay).

I'm always using High Performance mode.  I could certainly try disabling the Origin overlay but considering sometimes for no reason the game runs normally and the rest of the time it doesn't, I have a hard time believing that will fix anything.

Alright just confirming that disabling Origin in-game did not work, and neither have any of the other suggestions in this thread.

Short of going back to 8.1, does anyone know how to fix this?

Even though it would be alot of work, I would personally do a clean install of Win10, as the "upgrade" you did was nothing more than a gigantic Widows Update.  When I upgraded to Win10, I reformatted and did a clean install of Win10 the same day.  This will allow to make sure everything is installed correctly, and when you start installing drivers, etc, they will be correct and you will be able to clean install EVERYTHING.
