But VS 2012 Express sure produces fast code. I was experimenting with a sqrt routine that uses Newton's method. It was so fast that using the API routine GetSystemTimeAsFiletime measured 0 secs elapsed time. Compiled with VS .NET 2003, the same routine took about 2 ms. The compiler now intermixes FPU and MMX instructions, which may be the reason 2012 is faster.
