I will chime in once again.. texture memory texture memory texture memory!!!
They recently upped it to 8MB for the CVs and so everyone would run high res art. Next you'll need 16 or so unless they use the AGP architexture(requires being programmed to be used). I have a V5, so I'm not worried. But don't forget that little stutter you get everytime a new plane gets loaded into your memory from your HDD. Multiply that by, lets say 4 schemes per plane, within a single square mile you have 20 bandits within eye shot. By the time all those textures are loaded, chances are you're shot down.
Happy slide show!
