Neil, my friend, FM is slow regardless of the number of leagues and db, using above-benchmark laptops I’ve owned over the years. I play saves ranging from 4 to 40 leagues, from small/national to large/customized dbs, and the slug fest starts during the first season and gradually gets worse into 10 seasons.
Yes, FM22 is a little "faster" compared to prior FMs, but still, I’d estimate 60% of dead time compared to 10% in other game genres. I'm probably an outlier in my high expectations though.
The only drastic solution was those nasty hacking apps to warp speed the game which I haven’t used in ages because clicking and crashes were a problem. Yet, that technology is something that your dev teams could look into for inspiration. THAT’s the speed I’m talking about!…
