DirectX Managed


Hi,
It's a great pleasure for me to see that David Catuhe from Bewise steel keeps DirectX managed to the top level. I've seen David for the first time at the first North Africa Developers Conefrence in Tunis. His DirectX Managed show was excellent. In one of his recents articles about graphics under .Net (see it here: http://www.techheadbrothers.com/DesktopDefault.aspx?tabindex=2
&tabid=15&AId=47)
he was describing one lack of performance issue Managed DirectX developers have to face, and thus he proposed a way to improve the performance.

Explaining how the using of tables slow down the program because of two phases of unmanaged resources manipulations, he recommanded the usage of GraphicsStream. Moreover he showned a way or using unsafe code so that the execution become four time fast.
