The fact that so many things were apparently changing in the lead up to the final RC is disturbing because surely they should have begun with a coherent plan for the UI in the first place? The mind boggles as to what they are doing.
I never had any real issue with win8's UI. It wasn't exactly pretty, but it was functional. Win10 is outright broken, with the way you can't really tell which window is active, and just general sheer ugliness on top of that - white title bars for native windows apps, whichever the hell color coders feel like for metro apps (including edge, which has a GREY bar, YUCCCCKKKK), and so on.
MS is such a headstrong company, they REALLY don't like learning from their mistakes. They'd rather just shove their shit down everybody else's throats and have us swallow willingly. They HATE having to admit mistakes, and they hate even more to go back on their own decisions. Like the way they super-grudgingly re-introduced the start menu - except not really, it's just a scrolling version of the start screen from win8, not the hierarchical menu of old where everything was grouped and easily sorted through just by looking at it.
And the windows desktop, you can't have the nice aqua theme from win7, because that would mean they would have to admit they were wrong in removing that in win8, so they tinker with the win8 theme instead and F it up even more.
MS is such an annoying company, if they weren't so irreplaceable in the PC gaming scene I totally wouldn't bother with them at all.
Yeah except now everything is made for ants. The only real solution is for lazy devs to start coding for high dpi scaling. I'm looking at you valve and blizzard.
There are good scaling kernels that don't blur the source material - or well, not unless you scale it by A LOT anyway...
I wonder what they're using - straight GPU rasterizer hardware scaling maybe - IE bi-linear interpolation? That would indeed look like utter shit.
