What does "clear" mean under Camera.Render -> Drawing in the profiler

Hello,

I’m developing an android game and I’ve noticed a bad frame rate on my lower end device (kind of obvious). I decided to see what it was all about I have found that every second to every 2 seconds I get a spike which is causing my low frame rate. The spike is from “Camera.Render → Drawing → Clear”. It spikes to 70% - 95% of my total CPU and takes anywhere from 50ms - 65ms.

Everything else looks reasonable, but I don’t understand what clear is. Is this something I can make more efficient?

Any information on what this “clear” is would be great.

Thanks

I was told that it is the same as the clearing flag in the Camera inspector settings. The reason why it takes super long on my specific device is unknown, other then poor specs.

Make sure that your first camera clears using solidcolor. On tiled renderers not clearing at the start of the screen requires the chip to load back colors from the framebuffer to the tile-memory. This is not fast.
