I will take path tracing dedicated card any day but there are none and no applications for it yet. Even pro software is still in infancy of adding support of the new RT hardware acceleration. Let alone games there is 1 remake that uses PT, the rest are hybrids that run like a potato anyway.
More so when does M$ actually plan to update OSes to 1809? Their infamous borked October update has still not been deployed via Win update and it has to be manually force installed. Stupid DX12, Vulkan tracing works fine on 1803. Why can't they release a DX12 update instead if they can't manage their Win updates to offer major updates on a timely fashion. Seems to me they are trying to skip 1809 straight to the next update.
Great... with Win10 they stopped offering standalone DX updates and instead one has to update the whole OS. What the hell M$.
