Even worse for a buff pilot, they are far too thick to see a target through in your bombsite even at 11k (and a teammate wanted to do a HALO drop of troops over a Vbase and he had to descend to 3k to see where to drop)!
I have yet to see these type of clouds, 3k ceiling? I flew through the clouds yesterday,as they were different than before the clouds had been turned off previously(to refine them I believe). The clouds I saw were around 11k but I believe they were closer to 14k? Doesn't really matter, it could be just a recollection thing. Any way, I flew just under these clouds and had no problem seeing base and or terrain features. Unless they have been changed since last night around 10 pm edt. Some times I believe that some folk suffer from the old "Princess and the Pea" syndrome. You see that your Frame rate counter takes a dive and thus an issue with game play. Turn it off or at least wait until you notice a problem in game play THEN turn on FR counter to see if that was the issue. This isn't directed towards the OP, but it could be the situation for others. Its a work in progress and progress is being made every update.
