There are standard libraries of shader functions, such as for Cg . But are there resources which tell you how long each takes... I'm thinking similar to how you used to be able to look up how many cycles each ASM op would take. There are no reliable resources that will tell you how long various standard shader functions take. Not even for a particular piece of hardware. The reason for this has to do with instruction scheduling and the way modern shader architectures work. Take a simple sin function. Let's say that the hardware has a special hardware to compute the sine of a value, so it's not

I have been fooling around with screen capture for awhile now and I managed to capture the entire screen, certain areas on the screen etc... But when I go into a game and try to capture the screen, it completely ignores the game and instead, captures the desktop (or whatever is behind the game window). Another interesting fact is that the same thing happens with the PrtScn button. Any ideas on how to capture a game's screen? vcsjones The screen capturing technique you are using works well for capturing things that aren't hardware accelerated. I suspect you'd have the same problem trying to

Good day, I am trying to display a real-time stereo video using nvidia 3DVision and two IP cameras. I am totally new to DirectX, but have tried to work through some tutorials and other questions on this and other sites. For now, I am displaying two static bitmaps for left and right eyes. These will be replaced by bitmaps from my cameras once I have got this part of my program working. This question NV_STEREO_IMAGE_SIGNATURE and DirectX 10/11 (nVidia 3D Vision) has helped me quite a bit, but I am still struggling to get my program working as it should. What I am finding is that my shutter

Which is the preferred approach for doing .NET 3D graphics programming: Direct3D or XNA seem to be the current technologies, but which is best for non-game related programming? Also, has Managed Direct 3D been discontinued? XNA doesn't really seem to be appropriate for non-game development. If it's not game related what is it about? If you answer this we might give you a good answer, anyway depending on the application WPF might be a good answer. Yap, too bad MS discontinued MDX. I'm currently using SlimDX for our non-game development. It's not a drop-in replacement for MDX, but at least the

How to query GPU Usage in DirectX? Specifically DirectX 11. If someone ever did it, could you provide me the code snippet? Vertexwahn Process Hakcer is able to do this.
