Ultra does not work with AMD RX6800M, AMD RX6900 XT

[Josh]

I've got a validation error occurring in the release build that does not occur in the debug build. It did not occur to me that I should try running validation layers with the release build, since I thought the code was identical.

This particular issue is fixed, although I still see a few problems with specific post-processing effects.

This was caused by an error in my code, not by AMD's driver.

Let's see who can spot the bug:

chaininfo.sType = VK_STRUCTURE_TYPE_SWAPCHAIN_CREATE_INFO_KHR;
chaininfo.surface = surface;
chaininfo.minImageCount = 2;
//if (USE_TRIPLE_BUFFERING) chaininfo.minImageCount = 3;
chaininfo.minImageCount = Max(int(capabilities.minImageCount), int(chaininfo.minImageCount));
if (capabilities.maxImageCount != 0) chaininfo.minImageCount = Min(int(chaininfo.minImageCount), int(capabilities.maxImageCount));
chaininfo.imageArrayLayers = 1;
chaininfo.imageUsage = VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT | VK_IMAGE_USAGE_TRANSFER_SRC_BIT;// | VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT;

if (device->queueinfos.size() == 2)
{
  chaininfo.imageSharingMode = VK_SHARING_MODE_CONCURRENT;
  chaininfo.queueFamilyIndexCount = 2;
  uint32_t indices[2] = { device->queueinfos[0].queueFamilyIndex, device->queueinfos[1].queueFamilyIndex };
  chaininfo.pQueueFamilyIndices = &indices[0];
}
else
{
  chaininfo.imageSharingMode = VK_SHARING_MODE_EXCLUSIVE;
  chaininfo.queueFamilyIndexCount = 0; // Optional
  chaininfo.pQueueFamilyIndices = nullptr; // Optional
}

chaininfo.preTransform = capabilities.currentTransform;
chaininfo.compositeAlpha = VK_COMPOSITE_ALPHA_OPAQUE_BIT_KHR;
chaininfo.clipped = VK_TRUE;
chaininfo.oldSwapchain = VK_NULL_HANDLE;

res = vkCreateSwapchainKHR(device->device, &chaininfo, nullptr, &swapChain);
if (res != VK_SUCCESS) return false;

Is it related to the chaininfo.minImageCount definition ?

Awesome, I'll try this on my RX480!

I have a 6600 now. Editor runs fine in debug mode but crashes in release mode with no messages...

Awesome; this was my next question about the editor, because I have a 6600 XT

Should all work. I expect everything to work on my RX480 as well.

Yep the editor starts for me now with the latest update. Before it appeared to do nothing after showing the splash screen.
