While the in-game mouse cursor speed is fine on my system, the camera rotation while holding the right mouse button is much slower than I’d like. Games like this typically include a camera sensitivity option but I don’t see one in Homeworld Remastered.
I found an option called mouseSensitivity in \steamapps\common\Homeworld\HomeworldRM\Bin\Profiles\Profile1 but it doesn’t seem to affect anything.
Anyway, I submitted the suggestion. Figured I should post it here for additional visibility.
