Several things might be going on.
The obvious, you have something else running in the background. \
For a long time there was a memory leak that after an extended period of time in the game it build up. Restarting the client cleared it.
Some addons have a memory leak, or memory leak affect. Reloading UI often clears that up
Of course there have been or seems to have been some server issues the past few weeks that may be in play as well. If it is not a memory leak then I would suggest a tech support ticket. They can delve into details of what is happening in your PC. Understand they want to test things out with no addons present.

The game has had a 30-50% FPS drop bug since 2.2. It doesn't affect all players. ZOS won't acknowledge it.
There are things you can do to mitigate it though:
