Just one comment about the content below. The C++ class example doesn't fit the argument, as in unmanaged C++ you explicitly make your variables reference or value based upon how you define them, allocate them, and pass them around. The default is value if you don't define any pointers or use any dereferencing operators.

If you want performance, write a shader and do your matrix manipulations on the GPU or call into a C++ matrix lib. I also don't really see why classes would kill performance really. Admitted, in C++ I used structs for coordinates and some own written math lib for working with those structs, however a struct is a class in C++ anyway (they're synonyms, IIRC) so why would: public class Vertex3 { public float X; public float Y; public float Z; } be slow in .NET? Graphic programming can only be done fast if you parallellize operations by delegating the tasks to specialized units, often a library written to do a given kind of operation really fast (optimized math lib) or for example a DX helper lib, or better: a shader which does manipulation of your data down the pipe in hardware. I don't think 3D vector math in C# will be that performant over a C++ version.
