Dear Frank,
I'm crossposting this to atlas-devel, and suggest that future
atlas-related technical discussions of the problem go there.
I have the same performance problem as you do. I have an NVIDIA 32Mb
graphics card, and I have the same problem. What helped alleviate the
problem a little bit for me was 1) generate a set of lowres tiles
as suggested on the Atlas site 2) use --geometry=256x256 in Atlas
for smaller window and hence less tiles loaded and less GL overhead.
3) use 800x600 resolution in flightgear 4) switch to a lightweight
Window manager session (such as flwm instead of KDE) -- the last
item is great for getting higher framerates anyhow -- KDE is quite
a hog.
Still, the fg framerate drops a bit, and the sound sometimes becomes
choppy. As a result, I more often than not prefer the pigeond.net
map in a browser window, and only fire up atlas occasionally for
a short period of time for checking out the airports/frequencies.
(If you're not running the CVS version, you're out of luck -- 0.9.8
had a lot of bugs in the multiplayer code!)
I was silent because the folks on the flightgear IRC channel
persuaded me that it is all normal because of the inferior graphics card.
But as you say you don't have this problems with the previous atlas
releases, maybe indeed there is a problem with some recent atlas
changes that cause the problem?
