The game didn't require any tinkering to work except the compability tool.
Playable aside from some performance issues
Pretty poor framerate given the hardware. Mangohud showed the GPU and CPU utilisation wasn't above ~50%, and the game was dropping frames like crazy. Turning off shadows helped a bit, but the frame drops were still pretty noticeable.
Loading screen for city battles can take up to a minute. Game runs flawlessly. Proton Experimental results in SEGV Fault.
Requries non-Experimental version of Proton.
Added ctrl and shift to grip buttons
Scaled UI in settings
Segmentation Fault
After playing some more, I would recommend just playing the Proton version. Like the other Total War ports from feral interactive (e.g. Warhammer 2/3 Total War) seems to suffer from the Segmentation Fault crash. In the other games it tends to corrupt save data (if I remember correctly). In this game I experienced one crash, but could resume playing normaly after restarting. But now 100 or so turns into the game, I can't finish the turn since the game crashes randomly before I can do everything. When playing the Proton version I recommend turning off "minimizing on focus loss" in the launcher, since minimizing can be a source of instability in my experience.
Longer load times than native port.
My previous report statet that I prefered the Proton version to the Native port. After some more time playing, I think both of them have their downsides. Both are good but not perfect.
In the Native port I experienced a issue with falsely detected double click, when clicking on armies/settlements, resulting in a additional menu opening.
The Proton version seems to have a bit lower performance and the loading times take longer. Some times they seem to be stuck, but eventually they will complete.
Both are perfectly playable, just not flawless. Switching between them only requires a ~120mb update, so try both and see which one you prefer.
When clicking on settlements/armies the game would often falsely detect a double click, causing the detailed setllement/army view to open. The Proton version does not seem to suffer from this issue.
The above issue is minor and the game runs just fine, no matter if you use the native port or the Proton version. But the detailed settlement/army view takes up alot of space in the middle of the screen, obstructing your view of the map. It is not a game breaking issue by any means, but it is inconsistent and over time very annoying. So I personally prefer playing the game through Proton.
But you can try the native port, and if you encounter this issue (and it annoys you too) just switch to the Proton version. Unlike other games the update to Proton was under 150mb for me. So you don't need to redownload the entire game.
Läuft auch mit Total Conversions perfekt
Works mostly perfect natively
Works perfect but with total conversion mods the game didn't work, but with smaller mods like blood mod or original loading screens it works perfect. (i only tried native version not with proton)
