So I tried these and with my setup (4870X2 and a 4870 trifire) I get CTD with BFBC2! Went back to 10.5s again and two hours of play and no CTD and no spawn lag.

Is it too much trouble to make drivers that are better?
I guess AMD doesn't really care about us older card users. I just don't see a need to upgrade when I can still play maxed out.

Oh well....
