JPGs are always a bad choice for use in gaming, because that format has no transparency.
And its only advantage over pngs, the smaller HDD storage size, doesn't help with the parallax RAM problem at all, because that problem is about uncompressed memory size, not about the storage size.
And in RAM there is no difference in the size between jpg and PNG.
So I realized that I really just don't have enough time to make videos. However I don't mind clicking stream and just letting people watch me work on my game. I don't really have a good microphone... okay it's a $20 headset so it's terrible, and I have no web cam. So the stream would largely be royalty free music and me working, with minor interaction. I guess the question is, would that actually interest anybody?
