This is clearly false. The Bevy performance improvements that I and the rest of the team landed in 0.16 speak for themselves [1]: 3x faster rendering on our test scenes and excellent performance compared to other popular engines. It may be true that little work is being done on rend3, but please don't claim that there isn't work being done in other parts of the ecosystem.
I read the original post as saying that no one has pushed the engine to the extent a completed AAA game would in order to uncover performance issues, not that performance is bad or that Bevy devs haven’t worked hard on it.
Wonderful work!
...although the fact that a 3x speed improvement was available kind of proves their point, even if it may be slightly out of date.
Most game engines other than the latest in-house AAA engines are leaving comparable levels of performance on the table on scenes that really benefit from GPU-driven rendering (that's not to say all scenes, of course). A Google search for [Unity drawcall optimization] will show how important it is. GPU-driven rendering allows developers to avoid having to do all that optimization manually, which is a huge benefit.
