hi, I am doing profiling on my android device, my phone is an old model released around 2017 , and the player camera is in idle statues , no any interaction and camera view change . from the profiling data , it seems take long time on render thread all the time, but I am confused about the Gfx.presentFrame (marked with green line ) has a long-short pattern, one frame takes 27ms ,but next frame it goes down to 2.07ms. Comparing with it , the ScritableRender.execute:UniverslRenderPipelineAsset_Render in the render thread seems stable , always consume 20+ms to send command to GPU. if the GPU is doing the heavy work, then why Gfx.presentFrame can be super faster in one frame suddenly, then slow back again ? there is no any change in the playercamera view during this time. I am wondering if this is a GPU bottleneck or plus Vsync issue ? can anyone help to explain it in details , thanks .
