Energy consumer is very high and my IOS was overheating so fast(about 10 minutes)

Hello @minggo,
Any update here?
My project has the same issue. The device was heating (especially iOS devices) while running the game.
How can I determine the bottleneck of this issue? Can you suggest any tool that helps me find the root cause?
Thanks!

Hi @greenmango2204, it is because there are some render passes, and every render pass will do store/load operation, which causes the problem. We will try to merge render passes as possible in v3.4.
