There's a quick review about Angry Birds for Chrome (the current best app :)).
First of all, the installation
It's easy. You just go to https://chrome.google.com/webstore/detail/aknpkdffaafgjchaibgeefbgmgeghloj?hc=hp-pr&amp;hcp=pr1-1 and click on "Install". The first time you open the application, it says "downloading the offline version", and it'll take about 2min to finish, and then you can play even offline.
Now, let's talk about the FPS
I'm running the game from Ubuntu with Chrome on a netbook with 1,66ghz and a Intel Atom, and in the slow definition mode, it runs okay.
Also, I ran it from my desktop computer (Intel i5 with ATI 5850) and it was... JUST PERFECT!
Well, I don't have anything more to tell you about the game. If you don't know Angry Birds, you're welcome to the internet.
