I have Windows 8 64bit retail version. I dont see this issue in my system. I think windows 8 might not be compatible with some graphics card or requires latest graphics card drivers. Let hope Microsoft resolves this issue in windows 8.1 . Ded9
It's not that you are not having this issue, it's just you don't care of notice it (or you really have a shitty monitor). Just use the same monitor with default settings/drivers with windows 7 and windows 8 and you'll definitly see the differences when you are browsing with IE10 (at least with the desktopversion, I don't use the RT ****).
I too hope they resolve the issue with windows 8.1, but I doubt it will, as mentioned above by someone from MS, the windows 7 rendering is still available (but not used by default, and I can't get it the same through using the crappy cleartype adjustment wizard). So if it's still available then it should be a simple registry setting, so why don't they just tell us which setting(s) we have to change to get the same (font) rendering as in windows 7... For me Windows 8 is nothing but a lot of discomfort in comparison to Windows 7, haven't seen ONE advantage of windows 8 compared to windows 7 (but since I had a new computer and Windows 7 won't be supported that long anymore (directX for instance doesn't get upgraded) I had to buy Windows 8, and I'm regretting it more and more..
