Another question to all of you:I use REX and ASE and have just got a perfect theme with ASE's weather but notice that there's a drop in FPS when flying thru clouds. I presume its not ASE thats at fault but maybe the REX clouds. Any suggestions folks?Thanks a ton.Cheers

I'm not sure if you are using a newer ATI video card or not - but if you are, have a look through the thread titled "Bojote's Shader 3.0 Mod for FSX" on this page. Many ATI users seem to be reporting better performance with clouds after switching to the 3.0 shaders.Dave
