vertical sync not working (ATI graphics card on Vista)

Hi.
I’m having problems with vertical sync not working. I tried turning vSync on using ofSetVerticalSync and on the Catalyst Control Center options and the framerate of my application doesn’t reflect the screen refresh rate and i’m getting image tearing.

Its a ATI radeon 4830 running on Vista.
Has anyone had any similar issues?

thanks

Rui

so after a lot of searching online it seems that ATI radeon cards simply dont allow for vertical sync on windows vista…

this is not an OF issue but just thought it might be useful for other people to know this.
