My test uses reference types. Value types would copy across the whole type (e.g. a 4x4 float matrix would copy 16 times as much data as copying a 4 byte reference as in my test above). So actually the performance gain from avoiding properties can be quite significant on the xbox, when value types are involved. 3nixios: Actually I’ve been meaning to write an update to this post.

We also don't know how things work with caching, what sort of memory usage problems properties entail. And finally, I think it's just "good practice" to not use the Setter of a property when it is not needed. I Quoth: “Property: 85 ms, Field: 66 ms”
