About Metro:LL developer. Why does their last game run better on HD4000 and 4600 GPUs than on current gen consoles? HD4000 is comparable to current-gen specs, 4600 is slightly better.
Quote from 4A lead programmer:
"Intel HD 4000 is about on par with current-gen consoles, so what's wrong with it being playable? Yes, memory bandwidth is the real issue, so don't expect it to run 1920x1200 at 30FPS, but something like 720p is playable. "
Same goes for every other multiplatform title.

Coding to metal is bullshit, yeah You can achieve in some algorithms better performance on consoles, sometimes two times better, but its very rare case. There is no proof for this, not even one.
