I vote for a release very soon. We've made many improvements to load times, cars, performance, the gui, etc etc. I've now got a new shadow system working in SVN also. Here's all I think we should do before we release:

* make sure all car shadows are correct
* audit the car settings to make sure everything is looking good
* add a replay record/play option to the menu
* fix the problems with (what I think is Chris') revised texture code and resolution changes
* do some internal testing to make sure the game works even when installed in odd paths, and test the ports on more than one computer if possible. I can help test Linux and Windows.

Once we release we can continue to try to knock down the other bugs Chris has mentioned as a high priority. Before I forget, I'd also like to add another bug into our high-priority post-release bug list: if you start several new games without quitting, the framerate starts getting worse and worse. This may be a memory leak problem or an STL-containers-not-getting-cleared problem.
