Re: [pygame] pygame slow on linux (ubuntu)

["spotter ." <talonspotter@xxxxxxxxx>]

Things keep getting more interesting on ubuntu...I have tried
controlling the frame rate, as rene suggested, and on windows, it
works just like it should. The frame rates arent spot on but close
enough. I added the same code under ubuntu and even though I made it
so that it should run at 60, then even at 100 fps, it did not.

Here is some of the weird things i noticed from the get_fps call in ubuntu:

for the first 10 frames, fps is 0
next ten frames, fps is 21.367...
next ten frames, fps is 22.123...
next ten frames, fps is 22.831...
next ten frames, fps is 22.0264...
next ten frames, fps is 21.834..

and so on....

at this point I know something is very odd...later on the fps gets
even lower to 20 as I fire the
missiles on the ship.
