btw. I´m not sure but i was one day browsing bugzilla and reading conversation where some Nokian said that Bounce is not even rendered at default resolution. SO I´m just pondering that is there any reason to run games with native resolution if frames rate drop too low. For me frame rate is far more important than resolution. I doubt that people see any difference on animation or moving when you lower resolution (e.g.640x360) on this screen.

.edit
I was wrong and it is rendered at native resolution.
