People becoming wiser in order to notice the stupid things they did back in the young days. This doesn't mean that they really stop doing those things. Wise people still do stupid things, only on purpose.

What do you mean by "real-time performance"? If you expect that in Windows you are going to be disappointed. And drawing lines in Windows is exactly the same wherever the data comes from.
