      • Would it be a valid programming approach in XNA to have the main game's Draw function not draw anything, but use DrawableGameComponent classes to perform all of the video processing This would seem to make sense, because you have various screen types in a game, which could all be DrawableGameComponents, such as the startup screen, FMV screens, gameplay screens, etc. Also, would you use Drawabl

So if I havefor example a very large vertex buffer and I need to modify just one vertex, do I need to resend the entire model to the GPU Thanks in advance.

I wrote some simple code to check the keyboard state, and close the app if I hit escape, but that doesn't even work. I just assumed that this would all be handled for me, out of the box...

I wrote this in another thread I just started : I am trying to play RGB video at 30 fps, so I set the Direct3D device's FullScreen_RefreshRateInHz = D3DPRESENT_RATE_DEFAULT (which is 60 for most monitors) and set PresentationInterval = D3DPRESENT_INTERVAL_TWO.
