I know you specifically asked for a way to do this without
templates, but this was my first thought on how to make it work
(and I confirmed it):
##
import std.stdio ,
std.traits ;
class Engine {
int publicField ;
void enumFields ( this Self )

I'll try a different compiler, too.
It's the same issue with ldc
Have you checked your default compiler/linker args?

I had a performance problem with std.xml some month ago. It takes me a
lot to point out that there was a default linker param (in gdc dmd
under linux) that slow down the whole thing.
So maybe it's not a code-related issue, I mean :)

It looks like a syscall/opengl issue. You somehow managed to hit a dark
corner of GL driver. It's either a fallback to software (partial) or
some extra translation layer.
I once had a cool table that showed which GL calls are direct to
hardware and which are not for various nvidia cards.

Well the intersting question is, why is it slower? I checked it
twice, the data passed to the GPU is 100% the same, no
difference, the only difference is the stored format on the CPU
(and that's just a matter of casting).
It's not easy to answer similar general questions. Why don't

My assembly is pretty rusty and actually, I have no idea what to look for.
