All ways worked fine for me, try re-installing it.
Again regarding
Batman Arkham City: I have to say, whatever was causing the issues I described earlier in terms of choppiness on start-up with this game has pretty much abated. No idea what it was. I'd tried restarting the PC, closing other applications, updating drivers, but no joy. Then it just decided seemingly of its own accord to settle down and play properly.
That said, I do still quite strongly dislike the way the install and start-up are handled generally. Perhaps it's a GFWL thing, but after the install it searched for updates and told me it needed to update Live. Then I had to jigger around with signing in and out and restarting until it finally decided it was up to date. This repeated three or four times. No indication of how many patches/updates it was installing, and I was even wondering if the previous update had actually worked a couple of times.
And still now I have to wait for the rather long disk-check before the game loads (Securerom is it?) (I did find a way to disable the hated unskippable intro movies, but I had to change some file-names in the game's directory), then I have to wait to sign into Live, then it insists on checking for DLC... gah!
And to top it all...
you can't change any settings from within the game! You have to quit, open the launcher and do it from there and then wait for the game to load again. Makes checking performance issues with graphics settings a right PITA - and why it's not possible to change key-bindings in-game I can't imagine.
These issues do detract somewhat, but I have to say it really is an excellent game. I feel like I AM BATMAN in way that even surpasses what Arkham Asylum managed.
