Hello,

Sorry for the delay in replying, I've been away for a few weeks.

I've tried the resource monitor suggestion and I've moved the map around to see if is the tile download that's causing the read/write noise. After moving the map to an area that I've yet to fly, the noise does start up and I get 20-40 plan-G3.exe images in the resource monitor disk activity page/tab, mainly writing. It does seem to slow down after a while.

I don't connect Plan-G to FSX, I prefer to use it plan and then fly.  I'm using Microsoft Security Essentials as my AV -- it does a great job, it's lightweight and free.

I am guessing the noise is tile download and perhaps has something to do with the way the map data is written to my hard drive. It just seemed a bit agressive!

Once the tiles are downloaded are they stored on my hard disk or are they always streamed to the particular view?

Kind regards,
Liofa.

Hello,

I've noticed that when Plan-G is running my hard disk is constantly accessing in a rhythmic manner, 1-2 cycles per second in a loud grindy fashion. I don't seem to have any problems with other software. I've reinstalled Plan-G on a different drive, but I am still experiencing the same effect. This occurs both with or without FSX running.

Has anyone else noticed this? I'm using Win7 64-bit.

Kind regards.
Liofa.
