Whenever I restart my computer and open Unity to enter Play mode, the game’s FPS becomes normal (>70 FPS). However, when I add new things and repeatedly enter Play mode, the FPS initially stays high for a few times but suddenly drops to below 10 FPS. After that, entering Play mode continues to be slow. However, when I save the current project, restart the computer, and reopen it, the FPS returns to the normal level (>70 FPS). This causes me to have to restart my computer several times during debugging.
Is there any solution for this?
I suspected that other applications were using resources, but I tried twice not to open any other software during development, and the process manager did not show any other high usage software, and the sudden drop still occurred. Although the FPS is very low, the CPU and GPU usage in the task manager are not high. CPU usage is 19% and GPU is 32%.
Find out the problem first by using the profiler to see what that 133.5ms is composed of?
