I've experienced a lot more lag on my phone with Windows Phone 8.1 compared to Windows Phone 8.0. I've noticed this is a common feeling shared among users in these forums. The xbox music and games apps are noticeably more laggy and I am bored of seeing the resuming screen on my Lumia 625.

I've also got the Lumia 930/1520. I do not want to downgrade those as I hope to update those to Windows 10. However, with the Lumia 625, I want to downgrade to Windows Phone 8.0.

I'm wondering on how to go about this. I know I have to back up all of my data and use the Nokia software recovery tool. Is that all?

Using NSRT will only get you the latest available SW/FW. You will have to download the older version elsewhere and have the NSRT offline before flashing. I dont know how well your phone will come out of this move as I have never done it myself.

If all the steps have been done correctly everything should go smooth :) However it's always handy to check some vids on youtube or just reading up on how/what to do
