As in the title, the game drops to 7 fps as soon as I try to give orders to my infantry. I tried both balanced and fastest settings without success. As soon as action spots are not highlighted game starts running in 40-70 fps depending on the map size. I don't have a similar problem in CMSF2.
My computer specifications:
Windows 10
AMD Ryzen 5 3600
AMD Radeon 580 4GB
16GB RAM
