Frustrated with the low FPS in game currently I did some research on how to increase GPU performance on iMac and found that if you reset the SMC and PRAM on your Mac, this seems to increase frame rates in the game noticeably.
Before resetting I was getting a pathetic 10-15FPS at 1280x720, after the reset I was getting upwards of 40FPS (good for my 2009 rig) at 1920x1080 with my usual graphic and effect settings. I noticed the improvement immediately at the character select screen which was choppy before, and very smooth after.
Don't know if this is THE solution, but it definitely seemed to help my game run more smoothly.
Hope this helps some people and if any of the Zenimax staff read this please let the community know if this could have anything to do with the FPS problems.

What Mac do you have and OS X version etc?Day after doing this fix - I can log in and play the game at a normal 30-40FPS. Enemy players in Cyrodiil still load on screen slowly, and framerate stutter still occurs around larger skirmishes, but at least the game is playable once again and isn't running at 15FPS anymore...
What Mac do you have? MacBook Pro Retina?For me, window mode helps a lot, i have around 20 fps in fullscreen and window (fullscreen). If i switch to window mode, i get around 58 fps and everything is smooth, but its annoying to have the window borders active.

Some notes on full screen vs windowed mode:
Windowed mode will be faster then full screen only because it is drawing less pixels.
If the window is running under the OSX Dock the frame rate with be forced to vsynch. This will clamp the frame rate down to a fixed 30 FPS or less.
For the best windowed performance hide the dock or make sure the ESO window is above it.
Apple has had some bugs with the SMC and PRAM on laptop with 2 GPUs
( video cards ). In that case the laptop would default to the lower power GPU and not turn on the high speed GPU. Resetting the SMC and PRAM fixes this.
Think this might have helped me too, at least a little bit.
I play on a 13.3" macbook air and with everything on low or off, but with subsample on high and grass on + shadows on low and I get around 20 fps (but as low as 5 fps doing big sieges). As I just tested now in a solo dungeon I went from 20-something to 30 something with fps peaks around 50.
I upgraded to Yosemite and I'm running into a bad FPS spike. I can get 60fps without much problem until I get into battle or there are more than a couple of mobs and then it goes down to 5fps. That's right, five. It's make the battle basically unplayable. It misses keystrokes, get's my direction keys stuck sometimes... just a mess.
