AMD FreeSync Support On Linux?

[ssokolow]

VSync causes unpredictable response latency because timings become unpredictable in a multitasking environment like a PC operating system and, if the frame is completed even a nanosecond too late, it has to wait a whole extra frame to get to the screen.

The whole point of *sync technologies is to get rid of that last vestige of analog VGA scan-out (the fixed refresh rate, needed to prevent phosphors from fading in dumb old CRTs. It's basically to screens as MFM/RLL is to hard drives.)

Some people (including me and my brother) notice that latency and find it makes the whole system feel unsatisfying.

Of course, given my budget and my attitude on lock-in, I think I'll just wait until nVidia caves and implements DisplayPort adaptive sync and there's a decent supply of large-format 4K panels with support for it. (Large-format because, if I'm going to drive more than twice as many pixels as in my current two 1280x1024 monitors, I want to fit twice as much stuff without squinting... which means I want to stay around my current 85dpi)

Well i guess assumpation is because intel doing nice job on linux , but i don't believe companies by default anything until i see that.

Intel looks fine when they hold PC 95% CPU market and 70% GPU or somethin' But i also remember times what Intel can be when they start to loose some market percentage, lot of love for AMD was there

I'm confident that Intel will support the adaptive-sync VESA standard. They probably won't call it anything fancy though.

again

same old story amd

Doesn't FreeSync have a ghosting problem? Also push more into the driver than G-Sync with monitor modules?

No, that's because the ASUS is the cheaper TN panel which has a better refresh rate but sacrifices colour accuracy and contrast.

$499.99 27" ASUS 144HZ gaming Monitor. Has the backlight strobe feature.
$999.99 27" ASUS 144HZ gaming Monitor. Has the backlight strobe feature and GSYNC
_____
$500 difference for GSYNC and a slightly different look to it.

...

And a GPU if you don't have Nvidia

It's a real shame that AMD doesn't take this FreeSync thing seriously on Linux, because...

I've been waiting for the perfect IPS + 144hz + Low latency + ___Sync monitor for over a year now. I wish it was FreeSync, and I wish that FreeSync worked on Linux.

I've been waiting for the perfect monitor for a while now. I might be willing to overlook GSync just to get this thing.

Is there any official word from AMD, yet?
Will FreeSync be supported in Catalyst and/or open source drivers?

Also, will the newly announced ?Frame Rate Targeting Control? (FRTC) be available to Linux users? (announced with the 300 series of gpus)

Phoronix: AMD FreeSync Support On Linux?

With this month's release of the Catalyst 15.3 Beta for Windows, FreeSync Technology support was added. Unfortunately, it doesn't look like any Linux support is imminent...

After reading http://techreport.com/news/29707/hp-...tops-this-year I am be curious to know whether there has been some freesync-related development in Linux drivers.

That doesn't seem to have anything to do with Linux.
But anyway Bridgman can tell you for sure re freesync status on Linux.
