Nice clouds there, Kurt.
At the beginning of the week we had that cloud cover type in real life. Not all that common here.
Once upon a time I knew what it was called. Oh well.
As for the "boing" sound, I haven't got a clue. You'll find it.
Now for the fun part - BECOME A STORM CHASER!Now that you've got a good weather machine for FSX you have to test it out.
Pick your favorite weather website and start looking for severe weather!

severe international weather forecastI don't recall how high the thunderhead in the background was, but the plane in this picture was at 44,000 feet.

I was over Louisville, Kentucky back in October.

Finding bad weather can also give you incentive to learn your navigation gauges.
I know we're not real pilots, in real planes, but
it is very satisfying to get below a storm cover and see your airport right where your navigation skills said it should be.
Realistic clouds also make it more fun flying to parts of the world that you may never get to see.
You'll now have the satisfaction of flying somewhere and saying " Right now, this is what it looks like in.....
Above or below the clouds, flying will be much better from now on.
BTW - You had asked about my having a lot of programs running.
Well, it works this way. So long a FSX has all the memory it needs, it doesn't matter too much what else is loaded in the computer.
There's a lot of talk about how much memory FSX will, or
can, use. For most people it won't matter unless they only have 4 GB
TOTAL.
Using a Windows 7 desktop gadget called
All CPU Meter I can keep tabs on how my system is doing.

Aside from whatever FSX needs, I always have side programs running in support of FSX - external instrument panels for my small screens, external GPS, PlanG.
The maximum memory usage from flying has been about 6 to 6.5 GB. My machine has 16 GB, so there's no problem running extra programs in the background.
