Re: Why are .Net UIs slower than C++ or classic VB?

I've noticed (for quite some time now) that .Net UIs are not as responsive

good old Paint UIs for examples).

They are also not as professional looking as the older applications and the
reaction times of the UIs is not professional looking at all.

Why do you think this is? Is it bad programming or is there something else
going on here?

I agree. I think (and hope) it's a lot to do with GDI+ not being
accelerated (and it probably will never be, as WPF approaches).
Something I've especially noticed is that resize logic for forms with
lots of nested containers is especially expensive. Very laggy resizing
of 16 or so nested containers of different kinds shouldn't slow a 3GHz
machine to a crawl, but it can and does!
