Re: [pygame] pygame 1.8 - problem with framerate

["René Dudfield" <renesd@xxxxxxxxx>]

hi,

this is probably because your computer has faster directx 2d driver
than windib driver.

We had to follow SDLs change of default driver, because the directx
driver is broken on some platforms.

However you can set the old directx driver.
os.environ["SDL_VIDEODRIVER"] = "directx"

I would recommend wrapping it in some OS detection - so your game
would still work on the platforms where the directx driver is broken.

Lenard: Maybe we can make this behaviour default in pygame 1.8.1... ?
What do you think?
We could use the platform module to detect if it's win9x, win2k etc,
then select the directx driver if so.

If you reckon, it's a good idea, I'll try and make a patch for the OS detection.
