The same could be said about all the other pre-alphas where they didn't fix it lol. Beyond alpha.. didn't fix anti-aliasing, same for Horizons.
True, but much of the stuff you've mentioned would be fixed late in a "Beta" phase or whatever pre-release
To my eye, the pre-alpha footage looks like quite alot of effects aren't there and the lighting looks off, but at the moment that's as relevant as saying "omg Frontier, why does it have the words pre-alpha in the bottom left hand corner, I hope you are going to remove that in the final game"
