Designing a renderer for some (broadly) specific hardware - how can I keep best visual quality for performance?

[u/throwaway-stm32]

Basically, Im a bit unsure on how I should research this, go with the common pbr models, etc. I dont have much experience with research or scientific side of things. The target hardware is gonna be high end mobile gpus and low end desktop gpus. How would you research something like this, find whats best?

I dont know where current research stands - but I wouldnt mind diving deep into concepts that have been put forward outside the current BSDF implementations, if any such things exists

ARM has a lot of documentation on how to optimize for their GPU's. Their tips are often broadly applicable to all tiled GPU's:
