It seems to me that landscapes in 0.9.7.1 were better.... more detailed and wow.... really cool. Is this normal or im having some troubles whit the game? I have an nvidia gtx 550, trheaded optimization is off and i have a clean installation of the game.
Couldn't say for sure from your written description, but I highly doubt it, since nothing's really changed in terrain generation other than the new version has a few new landscapes, like volcanoes. I think you're probably just suffering an effect of comparing too few planets. Try looking through the image dump thread and compare a wide sample from between the two versions. Also make sure you're only comparing procedural planets.
If you really are finding a meaningful difference in procedural terrain on your end, then you should consult the troubleshooting thread.
