I just learned there is a hotfix for AMD users.

Sorry but this 'hotfix' is about as useful as a cyanide pill, it does not do anything, the textures still pop in extremely slowly and the overlay (minimap and inventory screen) flickers so badly that i feel like i'm about to suffer an epliptic fit.
My pc can handle anything you throw at it to so it is not a issue with my hardware.
system specs:
Win 7 64bit
Intel Q9550 OC'ed @3.77ghz
Sapphire HD6870 Toxic 1gb
8gb Ddr2 1066mhz Ram
This is severly messed up, currently till this gets fixed i'm considering this a huge waste of cash.
