How could we manage device pixel ratio for the low end vs high end devices?

I need to optimise FPS for low end devices.

Hi @yash_mehrotra,

Check this article on how to manage pixel ratio: Device Pixel Ratio | Learn PlayCanvas

How could we verify for a high tier device as per the documentation?

If you follow the guide at the end, for low quality GPUs, you could use the opposite check for getting the higher quality GPUs.
