A relative newbee here so forgive me if I’m bringing up old stuff but I have similar problems. I have an 18 gig memory machine with 4trb of disk space, half of which is available to the page file memory and 4x 6 core AMD 4gb processors with a Nvidia GTX560 graphics card. So ok the Graphics card probably lets the system down a bit however, I’ve seen worse lol
Anyway, I get the same thing, It starts with 4 to 6 hours of game-play and then the game just grinds to a halt. In the old days of programing it would have been compared with the I/O bus filling up and not dumping. Anyone over 40 will probably know what I mean haha … so as Ii start to mine for minerals and build those templates that are supplied with the game, that 4 to 6 hour time span shortens considerably until it is counted in minutes rather than hours.
My fix has also been, save the game, exit, leave it until Stonehearth no longer appears in the ‘running programs’ list in application manager and then restart and she runs fine again for a short while. however, I now have 33 Hearthlings, 4 standard ‘living quarters’ one workshop for each of the trades except farming and hunters, a church and an Inn and she refuses to take any more, I can restart the game now and it will play for roughly 10 minutes before grinding to a halt with total lag out.
I have assumed this is something that is to be expected from an alpha game but as my lad reminded me, If it goes unreported, the developers won’t know so here it is folks, I’ll leave it in your obviously more than capable hands.
