Adicoto, do you know what vsync setting really does since you suggested it disabled? (I know what it is supposed to do in general.)

adicoto 6th July 2007 12:44 PM

As far as I know, the sync signal it's used when the video frames are not decoded at the required speed, so you can have a random image on the screen (like when waching in theater an old movie and the image goes up and down). This is what the signal it's used. But I never had any issues with that and I think this option can interfer with "try not to drop frames" option. My advice: if you have at least 1 GHz CPU, disable this option.

Yes, never had a problem with BSplayer and vsync, not on my actual computer, neither on my old Athlon 900.
The only program I had to enable vsync for, was PES6 :lol: (damn porting) :twiste:

What are the real benefits, when Vsync is disabled?

adicoto 7th July 2007 06:24 PM

You don't wait the synchro signal.

And that leads to...?

Less resources used.

Digiface 7th July 2007 07:07 PM

What are the main downsides, when vsync is disabled?

adicoto 7th July 2007 08:25 PM

Probably, on old, old systems, video gets out of synchro.

Digiface 7th July 2007 08:37 PM

ok. I disabled it. I got AMD Duron 1600MHz processor and 1536Mb's of memory.

adicoto 7th July 2007 10:04 PM

No problems sofar, yes ? Anyhow, there aren't many tests you can do, HD content won't run on such an low end PC.

Digiface 7th July 2007 10:57 PM

Can't really say anything yet. Time will tell.

Just tested 480p .mov trailer and it played flawlessly in BSPlayer and CPU was normal (moved between 16-33%), even in fullscreen. With QT Player CPU was nearly 100!.

720p clip also played flawlessly, but CPU went up to max 60%. Haven't tested 1080p yet.

adicoto 8th July 2007 04:36 PM

Interesting. Keep on trying.

Digiface 8th July 2007 05:01 PM

Ok, with 1080p CPU went up to nearly 100%. :?

Anyway 720p content still plays rather fine with my system and BSPlayer. :)

Tizio 9th July 2007 02:43 PM

Great results :o ;)

Re: VSync
 
I wonder how those consoles manage to cope with large 3D games and now also demanding media files with such a ridiculous ammount of memory and CPU speed [1] [2]. :roll:

Anyway, please stay on topic about vertical sync and stop discussing extremely hi resolution videos. Vertical synchronization should ensure that the video subsystem starts outputting every frame at the same time when the video adapter starts redrawing the screen. This should reduce frame tearing when half of the screen shows the previous frame and the other half is ahead on the next one. A PC has problems playing video files fluently because both audio and video subsystems run at their own speeds w/o sync.

The question is: Does this setting in BSPlayer impact the rate at which frames are drawn and how.

J7N, so you prefer vsync enabled?
