CopyQueue sample behaves inconsistently on Windows using Vulkan RHI

Open LB-KacperKapusta opened this issue 1 year ago • 1 comments

Describe the bug Upon launching the RHI > CopyQueue sample on Windows using Vulkan RHI it can be observed that the textures switch way faster compared to using dx12 RHI. Please note that the issue does not occur on Linux and the sample there behaves the same way the Windows dx12 does.

Prerequisites

  • O3DE engine available.
  • AtomSampleViewer project built.

Steps to reproduce

  1. Launch the AtomSampleViewer.GameLauncher.exe with "-rhi=Vulkan" parameter.
  2. Go to Samples > RHI > CopyQueue.

Expected behavior CopyQueue sample behaves the same across different RHIs/platforms.

Actual behavior CopyQueue sample behaves inconsistently switching textures way more rapidly on Windows while using Vulkan RHI.
