Blurry BGs in StepMania?

[Charlo]

I have a problem with BGs in StepMania. They are extremely low quality (it looks like 256 colors), and it's especially apparent when the BG is smooth; there are huge blocks of colors where there once was a gradient. I can't really tell, but it only seems to affect BGs that I've made, because I don't notice any lowering in quality with the ones I've downloaded.

I make the BGs in the GIMP and when I look at them outside of SM they're high quality. I don't know if it's a problem with StepMania or my computer, or the way I'm making them. I also don't know if this problem affects other people who play my sims.

Does anybody know how to fix this? Thanks for any help.

What rez are you running at and how big are the pics in px?
Most likely you are running the game as a much higher rez then the background files.

Nevermind, I fixed it. I feel like an idiot now.
