Vsync not working on some computers?

[IndieLöver]

Hi,

Trying out my current project on my mother's laptop, I noticed something strange. Even though I set the vsync on, it didn't wörk. Could it be that her laptop is so old/bad that it doesn't support vsync? Not that it has to anymore, I've already made sure the physics are no longer framerate dependant. Asking this just for curiosity.

Thanks

EDIT: I also changed profile pic recently. I had a much better wörm drawn, but I made it too large, and downscaling it made it look bad.

Yes, it depends. Some cards ignore requested vsync settings.

My old Ubuntu box became laggy to the point of not being usable (we're talking 1-5 FPS here, and not just the application requesting vsync, everything) whenever an application requested vsync. It really depends on the graphics drivers how (and if) it works.
