For anyone who needs to limit the Elder Scrolls Online's framerate any reason including tearing above your monitor's refresh rate, to make sure G-Sync stays enabled full-time, or raise the default limit of 100fps if you're using, for example, a 120hz or 144hz display, you can edit the usersettings.ini file in your "Documents" folder under Elder Scrolls Online\live. You can see how to find/edit it below, and I'll list the line you'll want to change after the picture. I'll add in some tech stuff but also I'll plain-English it if you just want to know what to change :

The line you'll want, by default (unless you have changed it previously) will be this:

SET MinFrameTime.2 "0.01000000"

This is the value in seconds, or in other words, a second divided by this number, that the game is allowed to render frames for display output (layman's terminology: the FPS limit ). You can change this to any number you would like by altering the number in quotation marks in that line. For example, 60 frames per second is 16.66e milliseconds mathematically, or essentially every 16.6 milliseconds with the 6 after the decimal repeating infinitely. If you wanted to limit your framerate to 60 fps to keep heat/power use down, you could change the line to look like this, instead:

SET MinFrameTime.2 "0.01680000"

Why didn't I say to just do sixes in there? Because the number is what the game engine is told to aim for, and the actual framerate will vary a little depending on what's happening in-game just by the nature of how it all works internally. By adding in a little bit of a lower limit, this will generally keep it from exceeding 60 fps, but not limit it to much less either. If you need to stay below a specific frame rate, make sure you add this kind of extra time buffer in the number you enter.

Quickly and easily, here are some of the common framerates you might want to set as limits, and a line you can just copy in to do so, pasting it to replace the existing one. Remember, you can always paste the stock one back if you goof it! You won't cause anything to actually go wrong if you make a mistake. To calculate your own, simply use a calculator to divide 1 (one) by the number of frames per second you want. Then, add around 5% (1/20th) of the number you get onto itself and use it:

30 FPS
SET MinFrameTime.2 "0.03450000"

60 FPS
SET MinFrameTime.2 "0.01680000"

96 FPS
SET MinFrameTime.2 "0.01042000"

120 FPS
SET MinFrameTime.2 "0.00845000"

144 FPS
SET MinFrameTime.2 "0.00705000"

For G-Sync users, add a little extra padding (~10% instead of 5% as described above) to make sure you don't have your framerate exceed your monitor's refresh rate, which causes G-Sync to disable itself temporarily until the framerate goes back down below that level. For 60hz on my 4K G-Sync monitor, I use...

SET MinFrameTime.2 "0.01700000"

...to ensure that it doesn't go above 60. Another easy alternative is to use a program like MSI Afterburner's "RTSS (RivaTuner Statistics Server)" to set a global framerate limit for any Direct3D/DirectX game, which usually is able to work within 0.1-0.2 FPS of the limit you set with the caveat that due to doing it at the OS level rather than the game itself, will add an extremely minor amount of input lag (generally, only tournament-level competitive gamers will even perceive this, but I did want to note it).
