  • XNA vs Intel 915G

    Last post by Scorchio
      • I was wondering if anyone has had any success with the XNA framework on a pc with the Intel 915G chipset. I have a user reporting an XNA-based program of mine is failing to start up due to it being unable to find a suitable graphics device. Reading around on various forums, I gather the shader support offered by the Intel 915G is somewhat non-standard, which may explain why XNA can't or won't use

      • Hi all Just a simple question: Is is possible to draw 32bit textures (A8R8G8B8 format) when the displaymode is set to R5G6B5 without any problems I want to know this because i'm working on a Texture class, and i want to know whether i should force Textures to be 16bit when 16bit displaymode is active. I know some quality is lost, but is it possible without any errors Thank

      • So using any of the many available tutorials on bitmap fonts, I can't find one that allows you to specify font size. The only way I can think to do it would be using scaling, but I've tried and the fonts look HORRIBLE. So if I want muliple sized fonts, is my only option to create a texture for each font size

I can see that the Graphics is obtained from the GraphicDeviceManager but how is this related to eachother. Im comming from WIN32 where there was something like a device context. Should i think in XNA along the same line Can someone tell me how the following terms a

Maybe you already see the problem. As my function gets called 10 times IN a milisecond (gets called in a foreach-loop) the seed value is 10 times the some. And the Random-Class isn't really THAT Ra

Then we can use it just like the create texture from file. Ok, here's the thing, just tell me that my understanding is wrong. Because i cant seems to make it works. I'm trying to c
