So, how taxing is filevault on a MBP. I'm thinking of getting the 15, and I know it asks you if you want to set it up when you first turn it on. Is it super taxing? Does it affect application performance?

It really isn't noticeable in normal usage. I enabled it when I setup my new rMBP and it seems fast to me.

Doesn't tax it much. On my late-2013 13" rMBP, speeds were:

1. 750MB/s read, 720MB/s write w/o FV.
2. 730MB/s read, 690MB/s write w/ FV.

So not too much.

I suppose my main question is, If I decide to load Diablo 3 up. Am I going to see an FPS drop with this on.

How do I set those three up. Can you do it after the fact as I've already setup and started using my new 2015 13" MacBook Pro.
Yes you can.

For Find my Mac, go to System Prefs → iCloud and scroll to the bottom to activate it.

For EFI password, boot into Recovery and once in Recovery, click on Utilities in the top menu bar and select firmware password utility.

For FileVault, go to System Prefs → Security and enable FileVault.

I had to perform a clean install on my week old rMBP because of the dreaded 'filevault encryption paused' error. Not worth it IMO.

So it doesn't apply today?
Based on what've read 20-30% performance hit does not appear to be accurate. I have FV enabled and there's a small barely noticeable difference. Or there was when I first turned it on. Now I don't notice anything as I've gotten used to the performance. I don't have the links but I've read some articles where the overhead is in the order of 5 percent (or in that neighborhood).
