Hi,

it would be nice to have a multithreaded openttd, which scales well with the available CPU(core)s. I understand, that this is a serious change in the code, but I think, it is rather nice and inevitable for future generations of cpus, which usually increase number of cores and not frequency.
I played a long time with an older version (<=1.2.0), which brought it to 13% cpu usage on 8 cores in a large "common" game, and just briefly checked out 1.4.4, which seems to get to 14% with the old game.

greetings,

Try compiling with a recent intel compiler, it can speed up the game significantly, well at least on intel cpu's. cant say much for AMD since i do not posses one.

A 'fully multi threaded' game is not going to happen though. but it does partial multi threading, i can often get 30 cpu out of 25 (100 *4) with 4 cores so its definately using more then one core, sometimes noticable with fast forward :p

andythenorth closed the ticket.

Reason for closing: Won't implement

Additional multi-threading is not a current goal for OpenTTD.
