Hi! I just read this now and im having the same troubles. I have it all optimized, my game is low poly, 40k prims on screen max 120k ( thats nothing still i guess ) and memory usage was cut to 1.3GB. MY phone heats up in 2 minutes and i guess FPS lowers by 15 because of the hardware limitations due to the heat. Do you have any suggestions on what i should do ? It heats up in every level, the more complex and the simple levels.. And im kind of on the edge of giving up as i spent 2 years developing this in my free time and now that its finally almost ready im having this heating troubles.. And i have a Samsung note10+ with 12gb ram and 2 octa core cpus.. i dont even dare to try this on some random mid phone.. Please if you have any idea what helps the battery drain im all ears.. thank you so much!
