Online:System Requirements

Knowing Your Computer's Hardware
It is essential to know what your hardware is before you can use this page. On Windows systems, the easiest way to identify your video hardware is to run DxDiag, which is short for DirectX diagnostic. To do this:
On Windows XP , click the Start button on the lower left-hand side of the screen, select the 'Run' option and type in  , then hit enter.
On Windows Vista  and Windows 7, click the Start button and type in   directly in the search box at the bottom of the start menu that pops up, and hit enter.
On Windows 8, right-click anywhere on the Start screen and select "All Apps" in the lower-right. From there, type "dxdiag" (ignoring the "No apps match your search" message) to search for it. When you've typed the entire word, it'll show up as an app and you can click on it to launch it.
You may be asked if you want to check for digital signatures. You don't need to for this, so click "No". Once you're in DxDiag, on the first screen (System) there will be a box called System Information. Within this box will be your processor and memory information. Under the tab 'Display' will be the information about your video card, in the Device box.

You can also use an external program to find computer details and more accurately determine if your computer is able to run Elder Scrolls Online.  

On a Mac, click About This Mac in the Apple menu. A small window will pop up showing your processor and memory size, click the button that says More info... to get your Mac's stats.

 

As of Update 9, ESO no longer supports 32-bit Mac systems, or Windows systems running DirectX 9.
