Why is farmville 2 slow to load and freezes constantly?

if you have upgrade to win 10 and not installed from a disc there could be a compatibility problem
the upgrade is not 100% successful as I have found out after 3 days of problems

Did you try deleting some files on your device, making some memory free?
Did you try to close some running program's in the back ground?
Dis you try to restart the game? just to mention 3 things you could do. Only one could already help.

Why don't you just try other browsers and use the one that works the best?

Have you update your Flash Player?
Your flash player maybe too old and need updating.
or maybe your internet connection is too slow to load the game

try to follow this article..

reinstall your flash player. or still you dont have a flash player to play games like farmville in facebook.. here is the link my friend, dont you worry.:D

Either you have a bad internet connection , Bad Internet Browser, or just your computer not good. i play the same game and it is kinda slow i think it could also be farmville it self, seems kind of unstable to me

It sounds like you may not have enough memory in you computer to run farmville. I have 2GB in my computer and it runs a little slow when playing farmville.

* If it's a flash player problem, try this :

1. Install the latest and updated version of Adobe Flash Player.

2. You can get it from :
http://get.adobe.com/flashplayer/ (Slow URL)
http://filehippo.com/download_flashplayer_ie/ (Fast URL)

3. After install, restart your system.

* If still the FarmVille page is not accessible, try this :

1. Open your web browser.

2. Goto Tools >> Internet Options.

3. Delete all Cookies, Temporary Files and History.

4. Apply the settings and restart the browser.

* If even now the page is not accessible, the problem is the busy server! Please try to Refresh/Reload the web page!

tell me if it not works...tc! :)
