FreeSync for Nvidia Cards
melkemind commented on 18 January 2019 at 1:43 pm UTC

Nvidia recently announced that the latest Nvidia drivers (for Windows) now support FreeSync. I've tested it, and it actually works very well. Have any of your heard if this functionality will come to Linux?

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.
