Hi John. I'm still having severe rendering problems to a degree where the 3D part of the screen is completely distorted and the application unusable, for example with the House Builder sample. This happens on several machines, with different video hardware, different versions of (WHQL certified) drivers and in different browsers.
If I can help with analyzing this problem or provide additional data, let me know and/or feel free to contact me.
Hallo Greg. Thank you for the nice review of the series. I really hope the articles motivate devs that are thinking about starting development of casual games to take a look at XNA, or maybe even attrack completely new developers. It would also be great if your coverage generated additional feedback, I'm always glad to receive comments on the articles.
