Re: How efficient is fragment discarding for large amounts of triangle overlap?

No so much "in the background" as just deeply pipelined.   We load triangles at one end of the pipeline, rasterize them to fragments, issue fragments to get colored, run the shader program, and finally...

Re: Optimal Screen size for Mali 450

It's also worth noting that Mali-450 can scale up to 8 fragment shader cores, so if you really want to push lots of pixel effects (resolution or more detail) it is definitely possible. 1080p isn't...
