Our Renderer is very new and all 10 previous techdemos run on Graphics Queue and have Graphics work only.

I spent a few days adding multi-queue submission to YugenRendererBackend or as we like to call it YRB.

Also spent good amount of time completing our SPVReflector to deduce SPIR-V (generated by HLSL) DescriptorTypes.

Thanks to this wiki page by DirectXShaderCompiler.

Finally YRB now has the feature to submit to different queues and submit compute work and put Cross-Queue barriers.

Here is our 11th TechDemo which is updating 2 milion cubes positions in a Compute Pass and Will Render them instanced in a Graphics Pass.

Also there is a flag to enable/disable using Graphics or Compute Queue, I didn't expect much difference due to several reasons:

1. The job is heavy but the CommandBuffer is actually light-weight (Dispatch+some setup)
2. Our 2 passes are linear and dependant on eachother, so nothing good unless we try async compute in a more complex rendering pipeline.

#if USE_COMPUTE_QUEUE > 0
        YRB::ComputeQueue_Submit(si);
#else 
        YRB::GraphicsQueue_Submit(si);
#endif 

There seemed to be no difference as expected :)
