I can confirm this I once made a set of routines to give formatted text on the screen using LineA code. Later I rewrote the stuff to use only VDI routines. It turned out to be faster to use the VDI instead of the LineA? Never bothered to figure out why this difference, but I learned to handle VDI calls and still get reasonable speeds. The trick is not to use them to much be only when you really need them. This is ofcourse a useless statement but if you program carefully VDI is fast enough for general purposes.
