BW, Have you beefed up the gfx since beta?

I was running a smooth 40 to 50 fps on low/med settings before launch but now with everything on low I'm hitting between 3/4 6 max

I have had a fiddle with the settings but it seems changing from max to low makes no difference to my frame rate, which seems odd!

HELP!

I have planned on buying a new PC but wont be able to get it for at least a few month :*(
