![]() Yes, alessiot89, but I will use WARP as programmer, end user cannot use it, end user will use a "Microsoft Basic Render Driver" and it work, but slow, end user will not use my program with this rendering :)Īctually, what I was saying is that if you happen to be using a video card that is below Direct3D hardware feature level 11.0, there won't be a DX 12 driver for it. You can try to use WARP for simple samples, the CPU should perform well enough. Thank you Chuck Walbourn, but, for example, I can`t install latest Intel chipset drivers (which contain a GPU driver) for tablet, I get error, that tell me "You need use a vendor specific drivers". May be have a sens to use already existing GPU driver interface (which used in DX11) in situation, where DX12 compatible driver not found in the system and programmer ask D3D_FEATURE_LEVEL_11_0?Īlso, while it's not a strict requirement, no hardware vendor we are aware of is planning a DirectX 12 driver for a video card older than Direct3D Hardware Feature Level 11.0. So, if we have GPU, which has hardware level DX11, we call D3D12CreateDevice() and pass it D3D_FEATURE_LEVEL_11_0, which is tell it that we need DX11 only features, why we get an error?Īs I understand, the problem is in GPU driver? So, all vendors must update them? Is it`s real? There are additional features available for GPUs that support feature level 12 and 12.1, but the current set of samples do not make use of those features. Otherwise it would have needlessly required everyone to buy new graphics cards. This is how we made DX12 available to the majority of the GPUs already out there. Note that we pass in D3D_FEATURE_LEVEL_11_0 to the CreateDevice function in the samples. DirectX 12 only requires "feature level" 11. The difference between runtime/API version and feature level is one that has confused a lot of people. ![]() ![]() Some time ago, in on previouse issuse, Bob Brow wrote this: ![]()
