Unfortunately this is a little beyond my current technical expertise. Based on your computer hardware there shouldn’t be any compatibility issues.
I’ll check in with someone from the dev team and see fi they have a solution. My main tip is always to verify the game installation in Steam (which you’ve done), and updating all available drivers.
We haven’t declared the Steam forums “obsolete”, but we wanted a more centralized forum where we could engage with the community. Hence the Funcom forums.
