Did it used to work on the same laptop?

When you uninstalled drivers, did you try uninstalling with Display Driver Uninstaller?

Uninstall from Control Panel
Restart into Safe Mode
Run DDU
Restart
Install latest package
----
Perhaps you could try 6month or so old drivers if 350 are being pains? Do a clean wipe with DDU again before loading them though.
================
You could try underclocking the 850m a slight hair. Like 10% Core and Memory.
Afterburner, nVidia Inspector or other tools should allow it.
Don't install RiviaTuner, if you do make sure it's set to Detection Mode = None or it causes problems with Origin in Game.
Have tried clean install of Video drivers after running DDU, both newest and legacy (344.48) version.
No difference.
Have tried undeclocking GPU approx 10% (90 MHz)
No difference
Still seems like PvZ GW wants to use Intel Graphics 4600 instead of NVidia GTX 850. Is there a setting in PvZ GW where
I can choose GPU? (e.g. command line, registry entry, config file, etc.)
Unfortunately no option in BIOS to disable Intel 4600. ☹️
Have tried disabling drivers, but no difference.
Please help.
Wow I completely missed that on your error message.. it is using the intel. Sorry about that.

nVidia Control Panel -> 3D Settings -> Program Settings -> Add Program (PvZ) -> High Performance Processor
----------
If it still wants to use the Intel.. some ideas:
Uninstall Intel Drivers from CP. Restart, let windows pick up defaults.
Try the Intel drivers from the computer manufacture website.
Try the Intel drivers straight from Intel's site.

Getting Optimus to work right is a bit of a trial and error, I don't really have a text book way to fix that other than monkey with the drivers until it decides to operate correctly. It might require reinstalling nVidia Drivers after putting clean versions of Intels on.

Perhaps completely clean both off (intel and nvidia)
Load computer manufacture's Intel driver set.
Load nVidia driver set.
