My guess, is that your computer/gfx card, depending on their capabilities, will handle things well until you begin to overstep the limitations of the components. A gfx card with 256 megs of memory should be able to handle 80mg of textures without any problems, say. I don't want to sound here like I know what I'm talking about, because I don't, but anyway that's my guess. My style is just to experiment, and I've been really happy with the way LFS has responded to higher res textures, if only on my computer. I haven't heard many reports from others who are having problems (faint slowdowns for a few people) and it's strange to hear that performance has actually increased! I know that some games work better for me in 1280 x 1024 than 1024 x 768, I think that's the graphics card prefering to operate at that higher res, but maybe it's also the monitor. Maybe it's also the game. Too many variables to know for sure.
