Question Identifying Causes of Significant Frame Rate Drop on Specific Low-End Devices in URP Project

"In my URP project, after enabling Post Processing, I used Bloom to add self-illumination to GameObjects. I also used ShaderGraphs to create skin materials in the project. However, I encountered an issue on certain low-end devices where the frame rate dropped significantly. The highest average frame rate on these devices does not exceed 30 frames, while there is no noticeable difference before and after using it on other devices, which can stably run at around 60 frames. Here are my project settings. Could you please let me know what could be causing the significant frame rate drop?"
