85% seem kinda high to me. It has bugs, but it has not crashed or locked up me... and again I have not tried all of the features... but from my experience I think for the price of the upgrade it is "and is going to be one of the best purchase I have made. Hell, I have spent that much money on 3 or 4 good texture maps. I'm glad I have it, and when the patches comes out, it will be even better. Niles
