@ShEsHy Have you tried the FAF Nvidia Fix mod with other versions of Supreme Commander? I think it would work with them. All it does is put a single console command in at the start of every match. That probably is 100% compatible with other flavors of SupCom.
You can also enter the console command yourself, just press ` (tilde key) to open the console, then type it in. The command is:
d3d_WindowsCursor
You only have to do that one time per match. But you have to do it every time, which is why the mod is more convenient, because it does it for you.
