It's easy to confuse resizing with increasing detail. If you think of a simple black line on a white background, that's quite easy to re-size without a loss of detail. But you aren't going to gain detail either. Often, the image looks better at the small size.
Re-sizing a gradient works pretty good too. But a pattern is a different story. Look at the image I made. The top, #1, is a simple linear gradient zoomed from it's 100x5 to a 500x25 The second, #2, it the same 100x5 re-sized with Perfect Resize 7 (great results, though I do wonder why it re-sized the width to 504 instead of the 500 I set in the program.)
The third image is a 100x5 pattern zoomed to 500x25 and the fourth is re-sized to 500x25.
It would take a lot of testing to really determine how well it would work with a TG2 project. I would guess soft edges would look better but harder edges, like a terrain/sky wouldn't.
