I played and didn’t notice any lag. I’m sure if an ad pops in at the exact time you are dragging a letter or doing animations, it could stutter. It seems fine to me. That said I have really good network speeds and I was testing on a Google Nexus 9 tablet which is pretty a pretty good performer.

Update: The problem still persists, but I noticed something important:
The frame rate drops only when the image in the banner is moving. It moves up and down during the first 20 seconds of an impression (I set 60 seconds refresh time).
When it stops, everything goes to normal. It doesn’t occur during the loading process, I checked the events in the listener function. Even for video ads.
Another thing is that I set text only banners 48h ago but it is still showing image banners in my device. Might it be something in my code?
I’m using build 2016.3012

Animated banners can have a negative effect on frame-rate, however there’s not much that can be done about it except to do as you’ve done: Set banners to text-only. However doing so will most likely affect revenue as image banners usually pay more.
The time it takes to switch from image to text banners is out of our hands as it’s up to AdMob to make the switch. There’s nothing you need to do in your code.
