I mean it's all based on the state of the driver used with pre-release GPUs and often the worst GPU of the lineup.
You could say this are beta drivers, but that is somehow not something people mention.
I mean sure there was a lunch of arc mobile GPUs but only in some specific region which was neither the US nor EU, it's as far as I can tell bit like a closed beta release from the dynamics involved.
So shouldn't we wait until the "proper" market launch of the dedicated gpus in the US before taking it apart as a catastrophe?
And sure older Games might not run as well, may some will never (which doesn't mean they don't run good enough to be played nicleye). Maybe except on steam because of the emulation of older direct X versions being base on Vulcan, that will be interesting.
