Nvidia doesn't even support vsync correctly on Linux, their proprietary drivers are a mess when it comes to integration into kernel and tearing prevention on Xorg. So let's wait and see I guess

@melkemind As far as I know any details regarding support for Linux are not (yet) known.

If you want FreeSync, better get AMD which should implement it correctly. Even if Nvidia will implement adaptive sync through DP let's say, there is no guarantee it will work with compositors and standard Linux graphics stack. Given their track record of very poor integration (DRM/KMS, Wayland, PRIME and etc.), I'd even expect it not to. With AMD we know they plan to make it work. Kernel support is already in 5.0.

Gsync currently works on Linux, why would enabling adaptive sync on Linux not work? As far as I can tell right now AMD freesync suffers from all the draw backs that gsync on Linux does.

My next GPU will be AMD, but it would be nice if I could buy freesync monitors and use them until I am ready to make the switch.

I don't know how exactly the integration will work. I'm just saying with Nvidia it's always more risky, since good integration isn't their primary goal, if history is teaching us anything.

From my tests, I think it's definitely worth it for games with framerates that tend to fluctuate. If it ever causes trouble on the desktop or in a particular game, it's easy to disable in the monitor's settings.

I bought my monitor because it was an ultrawide (21:9) on sale. It just happened to have FreeSync support, so I never actually intended to use it back then.

Has anyone successfully got a second monitor to work with gsync? I have tried setting up the second monitor as a Screen 1 server and the main on Screen 0, but to no avail. Seems like the driver just won't allow two screens with GSYNC under Linux.. NVIDIA REALLY need to fix that!

It's a limitation of X. You would need the game to span both monitors to be able to flip. As of right now disabling the second monitor is the only option.

Just put my hands on an LG29wk500 monitor (21:9 - 2560x1080) with Freesync. Thing is, theres is no DP port. Just HDMI. Am I doomed or is it DP on the GPU, that matters?

You're not inherently doomed.

Does AMD FreeSync™ technology work over HDMI®?

Yes, FreeSync technology has supported HDMI since its inception. Many FreeSync certified displays have supported variable refresh rate technologies over HDMI since long before HDMI 2.1 was released and HDMI VRR was adopted. Buying a FreeSync certified display that supports FreeSync over HDMI, provides the immediate benefit of variable refresh rate, even if the display does not support HDMI 2.1.

I don't know about under Linux, and I don't know about with an Nvidia GPU (16:10 is more important to me than VRR), but it is theoretically possible.

In general, try to avoid HDMI at all costs. At least don't buy monitors that don't have DP.

Didn't buy it. Got it from/for work... I was just curious to test it.

There is a way to enable HDMI freesync, forgot how. It was mentioned over on Phoronix in past but good luck finding the details.
