The textures are the least of the game's graphical problems.
The draw distance LoD got cut in half and dipped in bleach in comparison to last year's gameplay demos, the lighting is okay but it looks downright awful at times, like a last gen game, especially indoors where it looks like it doesn't even exist, the art style change, making it more colorful and saturated, doesn't fit with the game's themes and universe anymore.
Look at the SoD trailer, look for the part with Dandelion, and the part with Triss. Their character models, textures and the lighting etc don't look that good in-game at the same scenes. I'm not even gonna mention the burning village with the Wild Hunt or the fire and water effects. Not to mention the lack of blood compared to the demos.
And we're not comparing them solely to trailers anymore, but the GAMEPLAY DEMOS from last year even, where we saw how it looked and played, at E3 and in the 35 minute demo.
It doesn't matter if people couldn't handle it now, they'd lower the settings and handle it in a few years when more powerful hardware comes out.
The game simply doesn't look anywhere near as good as it did in 2013, nor 2014. Except maybe the character models, but even that's up for debate. Someone needs to make a high quality 1:1 comparison of the game with the SoD trailer, E3 demo and the 35 minute gameplay demo, to put an end to all this.

IMO, not that great. I can't keep a steady 30fps on medium settings at 1080p on my i5 + GTX760. Latest drivers, patches etc. It doesn't look good enough to excuse the performance.
