Flipbooks lose quality between 4.6 and 4.7

Has anyone else had this problem? I have quite large flipbooks running in my scene (it’s a 2.5d platformer).
They were looking fantastic in 4.6 but now that I’ve transferred my project to 4.7 the flipbooks look lower in quality, blurrier, and generally worse.

Is there some setting I need to adjust to regain the quality of my flipbooks? Is there new settings in 4.7 that could be effecting this?

Thanks!

Turns out it was the resolution percentage in the engine scalability options. I beg forgiveness.
