It works pretty well for me (KDE Wayland session). I think the only remaining issue for adaptive sync is something with cursor. But it's being worked on.

See some details here: https://emersion.fr/blog/2023/hdr-hackfest-wrap-up/

I'm using AMD.

Games like Cyberpunk 2077 and Everspace 2 work with adaptive sync / VRR nicely for me.

Part 2.1.1 seemed to apply to me: https://wiki.archlinux.org/title/Variable_refresh_rate

Also, anyone using Gnome is out of luck as it still does not support VRR but may soonish.

On Wayland, you mean.

I think those focused on gaming are less likely to use Gnome becasue of that. KDE in general updates gaming features pretty timely.

They are now working on HDR: https://zamundaaa.github.io/wayland/2023/05/18/hdr-and-color-management-in-kwin

Uhmm, maybe, I searched rather quickly and am thus not too well informed.

Does anyone have an RDNA 3 or RDNA 2 AMD card? Can you please test if latest GOG version of CP2077 works with ray tracing enabled with latest Mesa and vkd3d-proton?

It hangs for me, but I so far didn't find anyone else with GOG version of the game to confirm it.

See: https://gitlab.freedesktop.org/mesa/mesa/-/issues/8857

I DON'T have these cards, however, I'd like to give you a tip for the future:
please always specify EXACT package versions to be tested. "Latest" is a VERY subjective thing.
And for anyone using Arch, there is also the 'testing' repo.
AND some people may see latest == git.

So really, just tell people WHICH exact versions to test on ;)

Too late, that bug was already fixed and it's working now. And when testing latest, naturally always test latest git.

Well, in any case, you should ALWAYS specify, because what's "obvious" is highly subjective ;)

Obviously Ubuntu 18.04 which seems to be the latest version GOG supports,

I'm still using it, so it must be...

It's been there for a long time I think. Nothing changed in regards to no Linux version for it, so it's "business as usual".
