AMD FreeSync For Tear-Free Linux Gaming - Current State In 2017

[eydee]

In the meantime, AMD GPU market share dropped from 25% to below 9% in a single year, so freesync is more and more irrelevant.

I didn't have much luck when I tried it a while ago. So it's only supported on Displayport, does that include passive displayport to hdmi adapters? Afaik they only work with displayport+ and put the displayport into a hdmi compatible mode...

FreeSync works over HDMI too (it is using a proprietary extension to HDMI spec).

I never tried it over adapters though, and I would not be surprised if I found out they do shenanigans that break FreeSync.

It got a firmware update after tft did review

That's nice. 48-144 with LFC is 16-144fps and that's not bad at all

Thanks Michael.

I just realized today also that the AMD OpenCL ROCm kernel supports FreeSync. So now I have full OpenCL and FreeSync support on Ubuntu 17.10... pretty, pretty awesome.

It might say enabled, but it's not going to do anything at this point. Tried it myself, and it's not working. We are going to need the userspace bits before we can enjoy Freesync on the open drivers.

Oh, dang :/

Hopefully the adaptive synchronisation works the same way so Freesync code works for Freesync 2 as well and hopefully it will work independently of HDR so that doesn't hold anyone back from using adaptive refresh rates on a Freesync 2 monitor in case it's not implemented by then.

Pretty sure Freesync = Freesync 2, only that the latter has a stricter certification process for monitors with some added requirements.

Hopefully... Still didn't get any official answer on that from AMD.

Cant see how they have a history of it as its their first freesync 2 monitors though

history since june 12 - more than six months

It got a firmware update after tft did review

did that update fix issue which made tftcentral recommend limiting rate to 100 hz (which will still make 48 minimum too high) ?
i guess new review is in order

history since june 12 - more than six months

lost me on that tbh!
What other FS2 monitors have they made before the chg70 range ?

Regards another review I guess so as there's a few tweaks ect that are in the update. Surprised tft hasn't updated the review and mentioned the firmware update/fixes

I know eventually it will work. But as the article says

While FreeSync on Windows supports HDMI outputs too, FreeSync currently on Linux will just work with DisplayPort connections.

So I'm curious about the state currently.

The thing is, I have a Dell SE2717H monitor which does not have Displayport input...
