I am trying to enable PureDevice for testing purposes, but i can´t seem to get it to work.
Is there sometihng i need to set it to for it to work?

{
DeviceWindowHandle = form.Handle,
PresentFlags = SharpDX.Direct3D9.PresentFlags.None,
BackBufferCount = 1,
PresentationInterval = SharpDX.Direct3D9.PresentInterval.Immediate,
SwapEffect = SharpDX.Direct3D9.SwapEffect.FlipEx,
BackBufferFormat = SharpDX.Direct3D9.Format.X8R8G8B8,
MultiSampleType = MultisampleType.None,
Windowed = true,
};

device = new SharpDX.Direct3D9.DeviceEx(new SharpDX.Direct3D9.Direct3DEx(), 0, SharpDX.Direct3D9.DeviceType.Hardware, form.Handle, SharpDX.Direct3D9.CreateFlags.PureDevice, presentParams);

What does "cannot seen to get it to work" mean? Please describe it better - are you getting an error? Is the app crashing? Is the code otherwise fine and working and problems come only when you include the PureDevice flag?

You also should check whether the device actually supports puredevice, in DirectX it's done by testing the DeviceCaps against D3DDEVCAPS_PUREDEVICE, but I have no idea how is this implemented in SharpDX.

Well it errors, when creating the device, it´s something either in the Device implementation, or in the Present.

And yeah i am trying to find that in SharpDX, and the only thing i can find is: http://sharpdx.org/documentation/api/f-sharpdx-direct3d9-capabilities-devicecaps

And well, i can use, SharpDX.Direct3D9.DeviceCaps.PureDevice , but that doesn´t return anything.

I thought it would be something like True, False. But then again, i don´t know how DirectX itself does in C++.

Can you please show an example of how to check if i support it.
I am brain dead when it comes to this. But it does hav, HasFlag, but don´t get how i am supposed to, let it tell me if it supports or not.

Yeah i know, or well, i know that it´s a very, Delicate state. Meaning, it turns blind eye to everything, and you have to be more vigilant.

But that being said, my "Rendering" if i even can call it that, only have 1 purpose.

Render an Image. No 3D, no effect etc.

So there shouldn´t be any problem


I don´t have DirecX SDK, never got it to work for me, and it said (It´s in Windows SDK now!) and i got that one, but no DirectX SDK anyway;P

I did:

using (device = new SharpDX.Direct3D9.DeviceEx(new SharpDX.Direct3D9.Direct3DEx(), 0, SharpDX.Direct3D9.DeviceType.Hardware, form.Handle, SharpDX.Direct3D9.CreateFlags.HardwareVertexProcessing, presentParams))
{
bool support = device.Capabilities.DeviceCaps.HasFlag(SharpDX.Direct3D9.DeviceCaps.PureDevice);

}

And, it give True.

Edit:

Probably true, but would atleast want to get it working just for the heck of it.

Hopefully it´s not.

And well i am trying to do that, but i don´t get how to check device capabilities before, setting the device.

Maybe like this:

CreateFlags devFlags = CreateFlags.HardwareVertexProcessing;
if (cap.DeviceCaps.HasFlag(DeviceCaps.PureDevice))
{

devFlags |= CreateFlags.PureDevice;
}

Though, that returns false for some reason.
