OK, having played with Ubuntu Linux for a while, I like quite a lot about it - but for some reason it seems to be significantly slower than Windows XP, which I really wasn't expecting. For example, using Celestia and rotating the Earth, there is a delay of 2-3 seconds before the rotation occurs. A first-person shooter game was unplayably slow to respond to the mouse and keys. And so forth.
I have no idea what I'm doing wrong, but I suspect that something is giving speed a hammering, and I have no idea what. It's a 2.8ghz processor with 1gb RAM and a 128mb graphics card.
I really want to try Linux, so any suggestions on go-faster stripes would be appreciated.
