Desempenho ruim do Google Earth

[Bruno Buys <bruno.grupos@gmail.com>]

Fala povo,
Estou tentando entender porque meu google earth está com um desempenho 
tão ruim. O planeta se move em atualizações bruscas, como se estivesse 
em câmera lenta, quadro a quadro. O correto seria poder movê-lo com fluidez.
O 3D da minha placa parece em ordem. Quando não há 3D o google earth 
avisa, ao abrir. E isso não tá rolando aqui. O compiz roda decentemente, 
o desktop cubo gira direitinho, tal. Estranho, o problema parece estar 
restrito ao google earth.
O sistema é debian sid, atualizado, rodando num notebook acer dual core, 
com 2GB de mem, kde 4.1 experimental, kernel 2.6.26.
Vejam algumas saídas de comandos para mais info, abaixo. Alguém enxerga 
algo a otimizar aí?
Valeu!
