I'm trying to animate a loop through a set of images at an average of
1 fps, convert them to textures and then map them to a quad.
I'm not loading them into memory at the start, but on the fly.
Running with only three images at 1600x900 the script dies within a
minute or so with a memory error.
I'm reassigning the texture variable (self.img) with each loop, and
have tried several ways to garbage collect it but
it appears the texture data persists until it overflows. Am I going
about this wrong, has anyone else encountered this?
i've tried:
self.img = None
del self.img
...etc...
It's important for this to be scalable, so loading them all into
memory at the start is not an option.
