Change log for February 17, 2019 Vulkan 1.1.101 spec update:

  * Update release number to 101.

Public Issues:

  * Make clear that memory types for imported host memory must be host
    visible in slink:VkMemoryHostPointerPropertiesEXT.txt (public issue
    897).
  * Make <<interfaces-resources-layout, WARNING block>> into a NOTE block,
    per the styleguide (public pull request 916).

Internal Issues:

  * Make <<textures-output-format-conversion, computation of derivatives in
    non-uniform flow control>> have undefined behavior (internal issue
    1367).
  * Make behavior, not just values, undefined for
    <<textures-layout-validation, reads from inconsistent YCbCr layouts>>
    (internal issue 1366).
  * Consolidate version and extension behavior documentation in the
    <<extended-functionality, Extended Functionality>> appendix, While a
    great deal of text was moved from other parts of the Specification into
    the appendix, this just serves to simplify and make consistent
    discussions of versions and extensions (internal issue 1473).
  * Add limits for slink:VkPhysicalDeviceRayTracingPropertiesNV in the
    <<features-limits-types, Required Limit Types>> and
    <<features-limits-required, Required Limits>> tables (internal issue
    1511).
  * Disallow <<memory-protected-memory, indirect calls within protected
    command buffers>> by adding valid usage statements for the related
    indirect dispatch and draw commands (internal issue 1513).
  * Add valid usage stataements to slink:VkGraphicsPipelineCreateInfo,
    slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
    slink:VkSubpassDescriptionDepthStencilResolveKHR, and
    slink:VkImageViewCreateInfo preventing the creation of a renderpass with
    attachments in formats that are not supported for rendering (internal
    issue 1552).
  * Qualify valid usage statements for
    slink:VkAttachmentReference::pname:layout parameter so restrictions only
    apply if an attachment is ename:VK_ATTACHMENT_UNUSED (internal issue
    1561).
  * Add valid usage statement for flink:vkCmdDrawIndirectByteCountEXT
    restricting pname:vertexStride to be positive (internal issue 1566).
  * Make the `VK_EXT_sample_locations` extension depend on
    `VK_KHR_get_physical_device_properties2` in `vk.xml`.
  * Rearrange and simplify the <<interfaces-resources-layout, block layout
    rules>>.

New Extensions:

  * `VK_NV_cooperative_matrix`
  * `VK_EXT_depth_clip_enable` (internal issue 1485).

source: https://github.com/KhronosGroup/Vulkan-Docs/commit/55220784e078fe3dad80e9520ca1d264f9b12b72

New extensions:
- VK_NV_cooperative_matrix
- VK_EXT_depth_clip_enable

General Discussion / Re: Optix 6.0 Path Tracing demo (with RTX support)

Really impressive Demo. Runs great on a 2080ti even in 4k.
Would be nice to get the manual controls of 0.1 or 0.2 in 0.3 as well.

Thanks. There's a new version of the demo out now:
https://ompf2.com/viewtopic.php?f=8&t=2158&p=5886#p5886

This includes filtering (with reprojection), TAA, and greatly improved performance for pre-RTX hardware. A 1060 laptop should now be able to reach 25fps.

- Jacco.

Geeks3D's GPU Tools / Seascape corruptions.

Hi,

There is a issue on recent Intel graphics (SKL+) on seascape demo.
Screenshot (occurs after couple of seconds): https://imgur.com/a/TiTj1dz

The reason is a float overflow if order of operations is changed by shader compiler.
There is a simple workaround for this by changing one dot operation to use precise float.

Instead of using:
Code: [Select]
float hash(vec2 p)
{
    float h = dot(p, vec2(127.09999847412109375, 311.70001220703125));
    return fract(sin(h) * 43758.546875);
}
This can be used
Code: [Select]
float dot_precise(vec2 a, vec2 b)
{
    precise float result = 0;
    result += a.x * b.x;
    result += a.y * b.y;
    return result;
}

float hash(vec2 p)
{
    float h = dot_precise(p, vec2(127.09999847412109375, 311.70001220703125));
    return fract(sin(h) * 43758.546875);
}
