Well things change fast I guess, now they prepare lots of libraries to work on all vendors cards, so maybe we come to a point where one can really play one game with two different vendor cards harnessing both’s power at once. DX12/Vulvan gen or the next after. It would be great.
I guess its a bit of a fight between the techs wanting to create great things and management trying to protect their buisness even by “unfair” means.
