After GU 14.1 for Anno 1800, it seems that the game starts to get laggy after you play beyond 1 hour. It is smooth when first loaded, but around 1 hour mark the game starts to have performance issue.
At around 1 hour mark, if you zoom out far away, you will notice ships movement start to get jitter (you can tell it isn't smooth sailing, freeze for that few milliseconds every second), and when you try to build houses you can tell the game responds 1 second slower than your command. It gets very obvious when you zoom in to production building such as farms and trying to put up the fields, the game either freeze for 3 to 5 seconds before responding to your command (building the field), or if situations get severe it will just freeze for more than 10 seconds.
These few days I try different things, and below is my observation so far:
1) The problem seems "cumulative through time", in other words you will have a perfectly smooth game when you first loaded your safe game, then the performance gradually drop as time pass. I try to force myself beyond 1 and a half hour game play today, and it just start to freeze the whole game to the point I almost need to use task manager to kill it.
2) I am using AMD 6800XT, so I did try with FSR ON and OFF, it does not make a difference.
3) It seems that if I lower down my resolution from 4k to 1440p (without FSR), the performance impact seems a little bit lesser in 1440p. It still lag/jitter, but not as unplayable beyond 1 hour mark.
4) DirectX11 seems to perform worst than DirectX12 (I am using DirectX11 previously, now I change to DirectX12). If i recall correctly, the game is not even smooth starting from the first minute if I use DirectX11 (which force me to try on DirectX12).
5) Although I have issue above, the game has not crash by itself, or maybe you can say before it even crash it is already quite unplayable.
My system in general:
- Intel i7-6700k
- AMD RX 6800XT
- Samsung SSD 1TB (2 drives, still with 150GB space)
- 32GB RAM
- 4k monitor
- Razer mouse and keyboard (in case their software got to do with this)
- My setting for the game is High/ultra in general, maxing most setting except AA at 4x. I did enable the high distance view, function that enable us to pan our camera view further (well beyond the general "Furthest" setting).
I could not find this recorded under Trello, so decided to post here. Appreciate if you can look into it, thank you.
