Make it so the server creator can only allow a minimum graphic setting to play on their server. That way all servers aren't affected and people running in lower settings can choose to go to servers that allow it. This would make it fair for people wanting to play with max settings and also make it so its not all servers restricting low graphic settings. Seems like the easiest fix.

Something to those effects

I know people have to play at those settings but its an unfair advantage and makes the game unplayable or frustrating as hell.
