Nope, as a gamedev I can say that it definitely is impressive.
As with all optimization it is hard: as you try to squeeze more out of the machine your code gets less and less elegant.

Still, in my experience any codebase that pushes a large amount of technical boundaries tends to be full of huge "WTF is this" moments that require explanation. It is an achievement if you can create a decently powerful codebase that can survive rapid changes and additions. It's much more common, but I've seen and worked on AAA codebases that would break if you blew on them.
