Problems with smoothing.

[[Unknown]]

Are you able to compile it (it's pretty easy to do so and Visual Studio is free)? If so, I can tell you what code to change and we can see if it'd be worth it.

I have a Core i7 Ivy 3.4 Ghz CPU, which is definitely on the high end still, and an NVIDIA 9800 GT, which is definitely on the low end now. I'm sure I could get away with it being a bit more aggressive in some games, but there are a bunch of games where I'd get unplayable FPS in certain sequences/areas if it scaled all textures.

By the way, it also has a limit on the number of pixels it will scale within a frame. If you have a powerful CPU you can probably handle a higher number, which will reduce how often you see pixelated graphics for a few frames.
