I might suggest getting rid of Voodoo (already mentioned in this thread), install the Nvidia patch (http://linkscoursefiles.co.uk/patches/L ... aPatch.zip), and update the video driver (available from the Nvidia website).
While I don't disagree with the above opinions, online photos of the Bluffs course seem to indicate the dry grass would be more natural. That probably depends on the season. They both look great, Sage!
