I just wasted over an hour of my life trying to resolve a problem with blurry ground textures, which suddenly resolved itself and I have absolutely no idea what combination of fs9.cfg settings and/or aircraft selection caused it or fixed it. My default aircraft is the Koolhoven FK58, a nicely detailed plane but not at all a resource hog and I've flown it before with no impact on ground detail. So I try a few .cfg adjustments based on what I read online, still blurry. Then in mid-flight I switch aircraft to Paul Clawson's basic B-18 Bolo and voila, the ground detail looks fine. Switch back to the Koolhoven and it's still good. If anybody's encountered this before, where do you start troubleshooting? What settings do you use to maintain decent ground detail?
