Vulkan status

[John_Alcatraz]

Ok, so the issues I was seeing with Nvidia seem to stem from having a dual hybrid GPU setup on my PC (AMD & NV, with AMD as the ‘primary’/output card), which seems to have made the NV driver do some weird stuff. In single-GPU setups we are seeing the same improvements as on AMD. Sorry for the false alarm! :eek:
As of why UE4 is not way faster in Vulkan, it’s a matter of changing how the renderer talks to Vulkan. To do so the best way for Vulkan, D3D12 & Vulkan, we’d have to basically break all the code and rewrite it, which is not feasible as it would break licensees and marketplace. So instead we do small changes/deprecate code paths, and slowly get there. But that’s the end goal, to have a fast renderer
4.20 is almost free of validation errors, so it has a lot of fixes.

Great, thanks!

Did you consider doing it like the new audio engine? So let people switch between old and compatible with everything, and new but breaking all old stuff?

Also, could you say if it’s making use of parallel rendering already and with what amount of draw calls you do your tests? So if you test with something like 30000 draw calls per frame, how much faster is Vulkan then compared to D3D11?
