It started out good for me:
but after opening the package, it has all been downhill:
I installed over the network after sharing the DVD drive in my other system. It got installed and I thought things would be okay but it crashes immediately on startup of the game. I get the setup menu and then get a windows dialog saying the game crashed and asking if I want to send a report.
So, I flashed the firmware on my DVD drive and now I'm trying a local install.
Edit: All is well. After installing it from the local DVD drive (after flashing my burner) things are fine.
Edit2: All is well except performance, that is. With next-gen enabled, even the menu is crawling (at 1920x1200 4xAA/16xAF).
