My iPhone 6 Plus I think might be getting too old to keep up with the graphics. I literally have everything on the absolute lowest it will go....even lowered the resolution. I've had the phone for over 5 years now (got it new when it came out) and had the settings maxed out back then. Over the years as my phone got older I simply had to just lower the graphics to minimize lag if there was any (this almost always fixed it). I've been lagging now for 3 days in a row and I just hope its not my phone....
