what is the average tri count of a level for ios if 20 levels are created?
You can have a million polygons if you like at 60fps.
It’s not how many you have, its how many you’re drawing at one time on the screen and how many at one time that are being processed that matters. You should read up a bit more, get a better feel for what games do. Feel free to ask questions that are more specific though and we’ll help.
