I recently just moved to Windows 7 and I noticed that many of my older third-party apps didn't look so good at the high DPI I had set (150dpi versus the typical 96dpi). After searching the web for ways to get my apps to look good again, I stumbled upon the "Windows XP style DPI scaling" option. I enabled it and suddenly the apps looked good again. While I'm happy, I'm also suspicious. What did I lose by enabling this feature? Could someone explain to me the differences in how the screen is rendered with and without this feature, or explain the trade offs of using it?
