Hi there!
I successfully managed to get the Age of the Ring 6.1 mod for RotWk running under linux (current wine 5.22 only) with full T3A Online support, dxvk, and everything running very, very well on ultra graphics
Under wine, I'm able to ping e.g. google.com with reasonable response times (10 - 20 ms).
My UDP port 16000 is open (ufw + rooter + ISP should not be the problem here).
I even tried it without FW at all and exposed host (just to be sure).
I can login in the game as well.
The only problem I face:
In the lobby I always get the "red" connection dot with constantly showing 1000ms ping.
Therefore (I guess!) the game kicks everyone out with the "out of sync" error in multiplayer mode after ~30 seconds. I could not observe any lag during that short period though.
I'm very unsure where that's exaclty coming from.
Regarding the port issue, there is only one hint given: The program seems not to able to determine the "correct firewall profile state" itself if I interpret that log entry correctly:
"00d4:fixme:hnetcfg:fw_profile_get_FirewallEnabled 18190518, 0031E5B0"
However, I could not find anything useful for fixing that yet.
I would be glad for any other hints regarding my (unique?) problem...
Edit:
The connection is now stable and green... I had to grant setcap cap_net_raw+epi wineserver and wine-preloader.
Everything runs perfectly stable and smooth for the first few minutes online. Still, out of a sudden => Dsync. Kind of sad :(
