Another patent has came to light recently that hints to the addition of hardware V-Sync to their next console.

The patent does provide a little insight though, and makes mention of something called "vertical blanking." What this does is fill in missing frames whenever the game drops frames, kind of like a safety net.

While consoles only had software V-Sync in the past, this patent about a hardware form looks interesting, despite the technology being readily available on PC for quite a while. Who knows if this patent ever gets applied to a console considering their limitations. But it should be interesting nonetheless.

Good almost every consoler is played on a HTS or TV having vsync would be excellent. Just lock everything at 60



...not much time to post anymore, used to be awesome on here really good fond memories from VGchartz...

PSN: Skeeuk - XBL: SkeeUK - PC: Skeeuk

really miss the VGCHARTZ of 2008 - 2013...

I thought PS5 was going to be made using AMD tech? https://www.extremetech.com/gaming/271483-report-amd-built-navi-for-sony-ps5-delayed-vega-to-do-it Vsync is from Nvidia right?

Aren’t most PS4 games using it anyway? Can’t remember the last game with tearing on screen. I’m sure this is more about some kind of adaptive Vsync. This vertical blanking sounds interesting.

more and more rumors about ps5, sign that it's not far away...😉

e3 2019 could maybe be a little bit to early, there are still many big games arriving for ps4, but who know what sony intentions are...

My guess is that the plan is to offer Free Sync support next gen, but that this hardware based v-sync will be available for those that don't own a free sync capable monitor or tv, so that developers won't need to implement their own software based v-sync solution into their games for lower end gamers. That way developers only need to worry about implementing free sync support into PS5 games, instead of needing to implement both free sync and v-sync. 

Not really. Having one doesn't negate the need for the other. 

 

Freesync will allow the display (TV) if the TV supports it to match whatever framerate the game is outputting. But the likelihood that such a feature gets supported in TVs is extremely low. 

 

Vsync is more like frame interpolation. Frames are injected where they would have otherwise been missing to prevent screen tearing an/or judder.

 

Right now Vsync is done in software. Hence we see it in some games and it's non existent in others. If Sony is really planning on native hardware based implementation then it means all games on the PS5 will support it and devs rather than code it in will only need to enable the required API for it.
