Under DirectX 9 ™ approximately 80% of all command buffer traffic sent to the GPU was shader constant data. Changing shader constants became a whole lot more tricky, as sub-optimal updates to constant buffers could have a very severe impact on the performance of a game. The only references i found online to such an issue was someone running the IDE inside a VM that did not have proper 3d drivers.Since the release of DirectX 10 ™ 3D programmers have had to deal with constant buffers as the way of passing parameterĬonstants to GPU shaders. Can anyone give my an idea what is going on here? Why can i only use Warp and Reference drivers despite having a DirectX11 capable Graphics adapter?Īny help is greatly appreciated. The sharpdx samples run fine on another computer with Windows 7 and Intel on board graphics. I already swapped Graphics cards from a Radeon HD 5450 to a Nvidia Geforce GT 460 to no avail. SharpDX is able to create the devices but as soon as a VertexShader is created or a SwapChain is set up i get DXGI_NOT_SUPPORTED or E_NOINTERFACE errors.
