Hey guys,
So I upgraded the project to Unity 5.3.2f1 in order to fix some some Shrunken related crashes. After doing this I noticed the game would crash at fairly random moments throughout the game. I then decided to run the profiler and start debugging the issue (since the crash logs appeared to indicate memory related crashes). It seems that the only significant increase in memory usage comes from the GfxDriver which consistently increases throughout the scenes (the texture memory actually drops over time, so it seems fairly unrelated).
However there seems to be little information online as to why the GfxDriver memory footprint would increase so dramatically over time / scene transitions. I’ve attached some screenshots of the profiler reports while the game is running, as well as a text log of the crash itself.
