i looked into this issue as i wanted to know if its a hardware- or a software problem.

the only other phone that contains a high res screen (852x480) togheter with omap 3430 is Motorola Droid (that i know of)

and apparantly the 2.1 update of android (that was released last year) for Motorola Droid ENABLES vsync. atleast thats what people claim on the internet.

so i guess it means the N900 should be up to the job as well.

if we dont get vsync for Maemo5 - it will be an essential feature of Meego.

PS. lack of vsync can be particularly disturbing while playing games or watching movies while being connected to the big screen tv.
