Missing ML would be huge issue, because that's like most advanced feature, which has real life benefits. I would also expect for Cerny to boast about it. If they feel like Tempest 3D is worth it instead of ML, than...not so sure, because that puts a lot of monetary demand to not have shitty audio.
But will see, so far, I am kind of confused, because that Geometry engine was present on RDNA 1, but RDNA 2 apparently has HW accelerated Mesh Shader (pretty much every feature you can get by software, but it suck a lot of power obviously)
But honestly Tensor cores is why RTX series, have bigger power consumption and if you run GPU on ungodly 2.23Ghz, maybe that's why they opted out.
Will see. But some things were missing from presentation which MS boast about...in advance let's just say.
But most importantly is that guy legit, you can throw shit on twitter without any proof, like you can see in Clown World thread and on Ree.
