Bethesda has stated that a patch is coming next week to fix the crippling lag issues in Brink. Because this is the generation where we cannot play videogames until two weeks after we paid $60 for them.
If you're playing on PC, there are a range of unique fixes coming in order to deal with sound problems, graphical performance, server browsers and memory leaks. The dedicated server is getting beefed up in order to improve CPU performance.
So, I'll bother playing Brink again next week. Check out the Bethesda Blog for more robust details.
