Hello Stuart, First thanks to you and to everybody who work on it. We have got now a huge improvement. However i am , now, a bit disappointed with these flickering ( too often, may be it is my graphics cards NVIDIA 7800 GS 512 mo) which decrease dramatically the result (mainly with Metar) . And which make me to come back to the 2D clouds, with the GUI preference. I can understand that, with that last patch you have tried to answer to the low cpu performance, when we are using old computers. It was the case with the old 3D clouds version and nobody apologized about it since we had ever the choice 2D clouds or 3D clouds. I did like better one of your previous version. Yes we had that ugly blue edge ( sometime only when we had a 2d Clouds layer behind), but now, i have blue edge randomly coming on and flickering, which is worth. Wont it be possible to have a version which will come to a better eye candy, even if it is more cpu "eater". ?
