Hello, i have a 16 core ryzen but widelands uses only 1 of those cores. I red in one forumtread that Widelands does not set single or multi core itself how can i make my computer use multicore for widelands?

Hi,
that info is probably outdated. Widelands 1.1 and newer always uses 2 threads, one for the user interface and one for the game logic.

Ok, well, the thread ruling the gamelogic hits the roof and slows down very much. i play an 400 x 400 game. Maybe i have to reset some effects. thank you.

Hello Crisis,
welcome to our forums. Especially for such questions it would be of great help if you would add some information about the OS you are using and the version of widelands.

How did you obtain the info how much cores Widelands is using?

If you are using windows 7 up, the device manager can tell you how many cores a process is using but that function is hard to find and has different ways to get it with each different version of windows. For Windows 10, there is a seperate utility available from microsoft developer that lists how many cores a task is using.I can't remember its name at the moment.


The aussies are coming, ya ho! ya ho!

Hi i am a native linux usr with mint21.3 on 64 amd ryzen 7 with 16core and 16gb. i have a icon for the system monitor in my taskbar and i see a large amount off CPU % use hop from one core to another exept when the messengerbox is open, then there is 1 core at 100% and it stays there. further i think to have read in a tread that multicore is NOT implemented by widelands at all. so the core hopping is what mint21 does. which thread i dont know, i looked for GPU and found about 10 links.

Meanwhile i discovered that the actual play time as given in the Panel is TO SLOW, it TAKES 2 to 3 seconds top count 1 second of play time but well, i have a map off 447x447 and 591 soldiers and the lot of buildings.

very off topic:

i do z80 on zx spectrum https://www.youtube.com/watch?v=0CctEdGIaCo

a small example of my work
