Thanks @asuessenbach for pointing out the missing `VK_EXT_validation_features` extension. I have made a few changes that might make a difference as follows: 1. Moved layer settings out of the constructor,...

Ok, I think I have finally figured it out. It appears that you _don't_ need to actually enable the `VK_EXT_layer_settings` extension in order to use it. I’m not sure if...

Thanks @asuessenbach for the info re nVidia GPUs. I have an AMD card and I guess this is the difference here. @SaschaWillems would you please test using this PR with...

@SaschaWillems I understand. However I’d still like to track this down if possible and you testing on Nvidia with vkconfig active would give more information. I can’t do this test...

I just added a minor hygiene change to use `vk::ExtensionProperties` vs. `VkExtensionProperties` in **HPPInstance()**. Also updated some comments and decided to explicitly request required GPU features for **debugPrintfEXT** as per...

When using an nVidia GPU with SDK 1.3.296, it slows down for all API versions. When using SDK 1.3.290 with the same setup (nVidia GPU), the sample works properly when...

> I tried to update the VVL docs for it https://github.com/KhronosGroup/Vulkan-ValidationLayers/blob/main/docs/debug_printf.md @spencer-lunarg thanks for updating the docs. This is the same doc I referred back to today when digging into...

@spencer-lunarg I have raised issue https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/8760 as requested. > so basically this PR is not fix/breaking things from my end... I agree this seems like something on the VVL side...

Following interaction with the VVL team, I think this is now ready for review. A couple of learnings: 1. The `VK_EXT_layer_settings` extension is trickier than I first realized. On Windows...
