Hi Mojave,
Did I understood well that in this version of Octane you have ported all the Octane cuda code to the new "RNDR framework" that provide a Vulkan backend ?
I yes does the GTX cards use also use also the Vulkan backend (without the RTX extension) and if yes is the vulkan backend better than the cuda backend on some points for GTX ?
If I'm curious, this is because I saw the Redshift guys were porting their cuda code to Optix for RTX support,
and they found good improvement for RTX cards but for GTX cards the Optix version is actually slower than the original cuda renderer,
so for GTX cards they fallback to the cuda renderer.
So I'm wondering if Vulkan have the same issue for GTX or on the contrary show some improvement over the cuda backend.
But anyway I'm happy Otoy choosed the Vulkan way instead of Optix,
pretty exciting, already found several experimental pathtracers implementation on github.
By the way if this version is ported to the RNDR framework, shouldn't it support other backend out of the box, as metal and x86 ?
