Well, speaking (if I may), on behalf of the whole gentoo multiverse(tm) I'm pleased to hear that Wine outperforms The Windows. And I am heartily sorry that the graphics on Lincity aren't up to snuff. We, however, aren't in the buisiness of making the games here. Let me suggest that you take the graphics request up with the developers of LinCity (
http://lincity.sourceforge.net/) or Micropolis (
https://en.wikipedia.org/wiki/Micropoli ... eo_game%29). They are in a better position to address the issues you identify. While there you might consider contributing to one or the other project to hasten their improvement. You might also check out Widelands (
http://wl.widelands.org/) which is a bit more graphics directed.
Linux, the OS for the obsessive-compulsive speed freak in all of us.
