no its not, i was just screwing around.
If i do change it, then the streaks wouldn't be drawn like they are now. however i didn't really notice that much of a slowdown until i turned. Then again i didn't have the FPS counter on.
I think the new way to draw it would just fade out each star depending on its brightness and how fast you're turning.
edit: just turned the FPS counter on and im getting 40FPS looking into black space, so i think the number is a bit out of the question. I also had the line effect commented out in the code so i didn't see how much that affected the FPS, but i'd believe it'll be less than 40.
