I highly recommend a brand new install for the beta. Start with just your favorite aircraft and no plugins. Good opportunity to reevaluate all your addons. So far found the new ground textures to be really good and I now prefer them over current 3rd party replacements. The color transition to the high rez orbit textures is much improved which should allow for more "haze" effects to be applied without causing color artifacts. (I could swear there is more visible haze now). The cloud textures are nice although I really need to see more in varied conditions. Oh yes, and no stutters when clouds are redrawn.
