  • Managed DirectX much slower than OpenGL

      • I'm trying to port a trivial 85-line OpenGL demo to .NET and Managed DirectX: http://www.ffconsultancy.com/free/bunny/ The program simply loads a mesh, does a little computation and then renders the static vertex data. The OpenGL code uses a display list and the driver is free to optimise that. In DirectX, I'm using compiled, write-only vertex and index arrays, requiring only 1 call to DrawI

      • Microsoft has claimed the Nintendo Wii as a "kids toy;" however, if XNA can produce graphics and push performance up to what the Wii is capable of handling (games like Half-Life, Sims 2 from most XNA performance claims), does that mean that XNA is a kids toy too

      • I have a 2d sprite and I have it so you can make it walk left and right and it animates a walk as it does it. It changes to a duck sprite when it is ducking and jump sprite when it is jumping. I cannot figure out how to make it jump though. The closest i've gotten is making it go up a specified number of pixels on the Y axis but it doesn't drop back down. How do I make it jump up then drop down (a

      • Sorry about posting a new thread here, but I'm hoping I can sneak in a quick one while no one is looking. Any word on whether the grammar will be included in the next SDK I see a reference to it in the HLSL appendix, but the grammar itself seems to have fallen off the bottom of the page. Cheers

      • The XNA Framework can't write text to the screen out-of-the-box (unless you forego all of its 2D and 3D capabilities, that is). A little group called Nuclex has put together an excellent text-rendering utility that integrates extremely well with the XNA Framework: http://www.nuclex.org/framework/fonts 1) Reference the Nuclex stuff (see the Tutorial) 2) Make an XML file and fill it with a few tags

It becomes much harder for groups of dispersed people to work together on a project without it. I unde

      • Are there any plans to provide XAML support in XNA I realize some things are probably foreign to XNA's current design (like vector support), but even a subset of its functionality would be useful. Today, many studios use swf's (with proprietary playback engines or GameSWF) for UI and HUDs, but XAML would be perfect for that. I have some itty bitty XAML support in my own MDX engine, but it feels
