To change the games FPS cap up to 240 FPS
Open the eso live usersettings.txt file

Find the line that shows
SET MinFrameTime.2 "0.01000000"

Change the number to the following:
120 fps cap = "0.00833333"
144 fps cap = "0.00694444"
240 fps cap = "0.00411111"
Setting the number below 0.00411111 automatically changes it back to that number. An example being 0.00000001
If you are worried about editing this file. some options are:
-Make a copy of the settings file and keep it in another place like the desktop. You can just place that file back and have all your settings restored the way they were
-Delete the file and a new one will be created once the game is started. All settings will be set back to default if done this way
If you are unsure of what is best for you:
-If you are using a g-sync or free sync monitor and have a graphics card that supports the type you have. Ideally you want to use V-sync setting turned on in game. That sets the games FPS to match that of your monitors refresh rate for every frame. It eliminates screen tearing entirely and looks really great and smooth. When a game can not maintain the monitors refresh rate it reduces the number by 50% and makes a matching frame for every 2nd frame the monitor produces. It keeps dropping another 50% for each time the FPS in game is not maintained. Still making the picture look very smooth and no tearing at all. The in game v-sync setting should be turned off for everyone else not using these configurations removing the type of FPS cap that it is.
-For regular screens. Having fps about 20 to 30 frames higher then the monitor's refresh rate is about optimal since graphics card frames and monitor frames are not lined up at the same time. Having the FPS the same as the monitors refresh rate is not ideal since the tearing of showing part of the next frame is repeatedly in the same location on the screen. It becomes very noticeable and annoying when it's set like that. Increasing FPS even higher will very slightly reduce tearing a tiny bit more by showing part of 2 frames much closer together when the screen displays that as 1 frame
-Other games usually have no cap. Reaching a FPS cap means the graphics card doesn't need to give 98%+ at that point. Temperatures, load, power consumption and even fan noises may increase. Similar to how majority of other games are by default.
-Do not worry if you are still not reaching 98% GPU load/utilisation in eso. This game requires a fairly muscular CPU to give enough info to graphics cards. Even when paired with some older graphics cards that are not sold any more
-This may also help with those experiencing frame stuttering if they suffer from it
-With all my testing. I can not see any kind of game issue by doing this. Tons of add ons and triple screen. No game issues at all. No changes to FPS on screen below the cap. Disclaimer, I can not guarantee it will work for 100% of people smoothly only because of things like If a graphics card is not working as it should by operating properly under full load. It may be to much for the graphics card and possibly cause a game or PC crash/restart. In that case the graphics card would do that in 99% of other games on the market. Or if you never reach the games default cap then you will not gain anything or have anything different happening.

If you are unsure about anything else. Just ask
