I opened the last build from this thread (not sure if that’s newer or older than the one in the other thread) and it looks like the device gradually runs out of ram, after which something kicks in and collects the garbage (although there isn’t a corresponding GC spike on the performance graph). During this, it appears frozen, and afterwards the performance never recovers (“System” activity on the graph seems to begin to spike at this point), but it looks like the memory usage starts to gradually grow again, eventually leading to another hang. At least from the graph, it doesn’t look like the garbage collector ever has a chance to run at all until the ram is full. (Edit: or maybe it isn’t garbage and you have a memory leak, don’t think there’s a way to tell from seeing this)
(the varying FPS at the beginning is during menus/loading; the steady FPS is during gameplay, the low FPS at the end is during gameplay after the “freeze”)
