Hi Everyone,
I am developing a 3d endless runner for the android os and I am having some very strange performance issues...
my game will initially run at 30fps on a low end device, 60fps on my higher end devices... as you continue to play the game the frame rate descends, after only a few minutes on the low end device the game will slow to an unplayable 8-14 fps on low end devices(totaly unacceptable) and aboout 25fps on the high end device...
I am pooling all my objects and have monitored for the garbage collector, he is nowhere to be found...
The issue is in my rendering, the update cycle is using a maximum of 3-5milliseconds...
I have sampled the number of milliseconds it takes to render the scene, and each subset of objects... any list of objects is always between 0-10 objects in length the time taken to render that list is ever increasing...
Has anyone ever experienced something like this / know of anything stupid I must be doing? it doesn't make sense to me that rendering the same scene would take ever increasing time!
Thanks for your help
here is a snippet of rendering code, it looks about the same for every object type
