We have a game that runs smoothly on a desktop, but essentially grinds to a halt on the iPad (both 3/4 and Safari/Chrome). We have used prerender to get our draws down to between 25-30 for the level(s) in question (approx 60 entities on each), however when running on the iPad we see the draws shoot up to over 250. This seems to be causing the problem, as there does not seem to be any significant system lag. Before we crack into the code to troubleshoot this, was just curious if anybody has experienced a similar issue and/or has any thoughts on why draws would be such significantly greater on the iPad. Thanks in advance for any suggestions.
