Pre-allocate Textures?

[Derric Williams]

Hello,

I'm attempting to use relatively large images (1536x1024) with the ImageStim class.  I've noticed that when I use the "setImage()" method to change the image, it takes about 150ms, so several frames are dropped.  Is there any way that I could pre-allocate or pre-convert these images to their textures to prevent this from happening?

Thanks,

Derric

I just noticed the "StaticPeriod" code.  I'll look into using that.
