Hello again!

Thank you for the follow up. Your latest log includes a new error,VK_ERROR_INITIALIZATION_FAILED. This message suggests an issue with Vulkan initialization or compatibility, on top of the “out of memory” problems from the previous log.

Check your system for VRAM availability and use, to confirm if it’s being cut short:

vulkaninfo > vulkaninfo_output.txt 2>&1

The resulting file should contain the following:

  • apiVersion: Should be recent (e.g., 1.3 or 1.4, as the SDK is 1.4).
  • driverVersion: Should correspond to the NVIDIA driver.
  • deviceName: Ensure your NVIDIA RTX 4060 is listed as the primary Vulkan device.
  • memoryHeaps - memoryTypes: These sections describe the available GPU memory. Look for DEVICE_LOCAL memory types and their sizes. The MemTypeIndex=1 from the original log refers to one of these memory types.
  • VK_KHR_swapchain: This should be present and enabled.

Also, since you downgraded the drivers already, please make sure that the process includes a clea installation, meaning, removing all remnants from the previous drivers, as these could still interfiere in the process.

Additionally, you could test with an empty project, to ensure the issue is not isolated to your active project.
