That is, when I turned vsync on, sometimes it'd drop below 60fps & so the game stutters for a little bit, which I didn't think was possible w/ C++.
I think it was because I didn't bother to batch any of my models, using a separate vertex buffer for each. I was gonna re-write it (doing better GPU management) w/ XNA, but just got side tracked.
Wouldn't that be cool? An XNA game performing better than C++ ?
The language is not gonna save you from bad coding.. Least of all C++.
C# and XNA likely will perform a lot better than your average game because they've optimized it to be easy. Writing a lot of what XNA does manually takes serious effort, and should be left to people that have lots of experience optimizing.
In many ways it's similar with C# / C++.. For a lot of stuff C# can be faster, simply because it takes a lot of effort to make the C++ faster (See RicoM and Raymonds blog series where raymond did a C app and Rico did a C# one).
