DX12 and Threadripper


I’m wondering if someone cares to explains if dx12 benefits or regress performance in DX12 games ?

In DX11 we usually get games to use 1 NUMA node, as per my observations, however when using DX12 titles like Metro or the division 12 i see game utilizing all treads evenly if i do not bind them with e.g project lasso.

We all know that only one NUMA only has direct access to pcie graphic card with passing the infinity fabric… does it mean performance from one CPU draw calls in hingered and make e.g cause stuttering etc…

Did anyone do any sort of good testing with multple CPU NUMA machines in threadripper ?
