MSAA anti aliasing is no longer available

[cafelasm]

After updating Grafics Drive to a certain version in 2024, an MSAA initialization error occurred and it became unusable. The specific version number is unknown. After upgrading to Windows 11 24H2, the driver was also updated and this problem could no longer be avoided.

Specifically, the following code that initializes an MSAA buffer returns an error:

========================================================================
[VC++]

D3D12_CLEAR_VALUE clearColor{};
clearColor.Format = swapChainDesc.Format;
auto msaaColorDesc = CD3DX12_RESOURCE_DESC::Tex2D(
  swapChainDesc.Format,
  width,
  height,
  1, 1, 16
);
msaaColorDesc.Flags |= D3D12_RESOURCE_FLAG_ALLOW_RENDER_TARGET;
const auto heapProps = CD3DX12_HEAP_PROPERTIES(D3D12_HEAP_TYPE_DEFAULT);
ThrowIfFailed(
  m_device->CreateCommittedResource(  // Error return 0x80070057
    &heapProps,
    D3D12_HEAP_FLAG_NONE,
    &msaaColorDesc,
    D3D12_RESOURCE_STATE_RESOLVE_SOURCE,
    &clearColor,
    IID_PPV_ARGS(m_msaaBuffer.ReleaseAndGetAddressOf())
  )
);
========================================================================

Is there any way to solve this problem other than waiting for a driver update? Or do I need to deal with the program I wrote?

2. Where are you getting this settings? Can you share the screenshots?
3. Do you still remember the driver version that you used before when it was working?

I have determined that Intel has no intention of fixing the bugs in this graphics driver. A bug-free version of the graphics driver is no longer available.
I will state in my published application that it is not compatible with Intel's graphics driver, and will fix it to use the software driver.
Intel's graphics drivers have had many bugs for a long time, and this is what I should have done from the beginning.
