It might be that they'll put more time and effort into getting it looking right once more people can run it at all, too. I'm not sure what percentage of PC gamers have sufficiently new/powerful GPU's to run it, but I'd suspect it's still small, and I'd think there's only so much time and effort that devs will want to put into something that most people won't see at all, when they could spend those resources for other aspects of the game (including other aspects of graphics) instead.

The one thing I would really like now is better audio. Both stuff like better 3D positional audio (e.g. Deathloop if you turn that setting on - although the setting kept turning itself off for me, which was maddening) and more varied and complex sound effects and music. It can make a huge difference, even when people don't consciously notice.
