I can point you in the right direction for OSG features but not general graphics. You'll need to do your own research, there is plenty of resources available on the...

I think it's important to differentiate between rendering on the GPU and copying of data to and from the GPU over the PCI express bus. I presume this thread is...

I had a quick look a the example and nothing jumps out as possible cause of slower rendering. I'm really busy with other VSG work right now so I'm not...

Another thing you could look at is whether the windowing system is doing compositing in which was the application is rendering of a buffer that is then used by the...

Another variable you could experiment with is different formats for the colour and depth buffers, perhaps the defaults chosen by the VSG are tripping up the driver into a slower...

Interesting finding. Intel and AMD Mesa drivers work fine as well so it:s not an NVidia specific optimization. On Thu, 18 Jul 2024, 12:15 Slaw6820, ***@***.***> wrote: > > https://github.com/vsg-dev/VulkanSceneGraph/blob/8a229b30637eea6fcfd9ace3d0745415dd563d7a/include/vsg/vk/CommandPool.h#L35...

I don't know whether we'd see adverse side-effects, one would have to get it tested on all OS's, drivers and hardware combinations with the full range of VSG applications to...

Thanks for all the discussion guys. glslang has been painful dependency to have :-| If there is an alternative for compiling high level shaders into SPIR-V comes into existence that...

I'm open to revisiting the use of FetchContent in vsgFramework, originally I was concerned about supporting older versions of CMake that widely used linux distro's were still on, but it's...

My Kubuntu 22.04 systems has CMake 3.22.1
