You can cheat this auto-set 30 fps by game use that:
We must go:
[disk]:\SteamLibrary\steamapps\common\Company of Heroes 3\sysconfig.lua
and we must change every line contain:
{ setting="FrameRateLimit", variantUInt = 30 }
change to:
{ setting="FrameRateLimit", variantUInt = 60 }
Only 3 lines has 30 fps limit, after that we're limited to 60 fps or more if you write correct value (You can write 30, 60, 120, 144 and 0 - uncapped fps).
For some reason file from SteamLibrary override setting in documents, this why people has problem and must every launch game again set up settings.
