By reducing rendering (no background, reflections, or animations), you can lower the game's power consumption and extend your phone's battery life.

I used eco settings from the very beginning of the feature when it was Introduced, right now I'm use to it with out it on the shot boost power side of things but would be nice to turn back ground off.  It's annoying.  It Puts me off.  When playing  bad I need to focus harder, and the back ground doesn't let me do that,  I get to a point where I'm squinting with a stressful aim decision, nothing concerning, that's just due to tiredness on some days, but it does get to that point where I start thinking I miss my background turned off,  But even having said that.  Im also getting use to that too. Because on most days I am still clinical even with the back ground on, But that's the only thing I would like to have changed to have the back ground feature working again. And If it ain't fixed sooner or later, it's still fine, doesn't change my love for this game. It's still the best snooker game online! And il still play it. But I hope that explains my point of view on it.   Cheers 💪
