Chrome 37 (the current dev channel) enables high-dpi support on Windows out-of-the-box (which might fix the issues you had with win8 mode -- at least, it seems to work for me).
I'll have to check which version I have. I just downloaded the latest consumer version. The experience also wouldn't reflect most of the users since they would just be downloading off the main page. I probably won't give this a try since desktop mode works fine for the most part.
Thanks for the advice!
