Ok, an interesting development. I installed the setpoint drivers, which was no fun, because it wiped my mouse's configuration from the last time I had installed them. Not a huge deal, but I'm not sure if I configured my buttons the same way. (Whoops) Anywho, upon launching the driver, I saw that it didn't have angle snapping (what logitech calls its prediction) enabled. So I did a quick paint test. It looked like this.

Much like the last. However, if you note, the two lines in the middle that are the least straight are two that I set my mouse's dpi to 400 for, to match the intellimouse. More on this later.
So, in the interest of true science, I then enabled angle snapping. This gave some interesting results.

Looks like wide ruled notebook paper.
So I'm not totally convinced that the G500 has prediction. My lines are straight with angle snapping disabled, but I realized that this could quite possibly be due to the fact that I use this mouse on a very high DPI. The first test was at 3000 DPI. When the mouse is maxed, it looks like this.

This is (EDIT: could be), in my opinion, notably straighter than the 3000 DPI test. I only have to move my mouse a fraction of an inch to make a complete line here. Given, I don't know much about mouse sensor laser things. Maybe there is a slight hardware prediction. However, from looking at the test with the enabled prediction, I'm starting to think that I just make pretty straight lines. I am also terrible at making loopty-loops. Even with a pencil, they don't look loopty. So I can't say for sure, but I'm not confident saying that the G500 has prediction.
EDIT: My opinion wasn't totally right after looking at them side by side. I need to get someone in here who is better at not pulling the mouse up when trying to make straight lines. Theoretically, higher DPI should mean straighter lines, as you are less likely to stray from a straight line over a shorter distance. I have poor motor skills though. :biggrin:
I had a cheapy logitech that actually advertised prediction on the box. My sister took it to college with her, but I'll contact her tomorrow to do a couple paint tests so I can compare a logitech with definitive prediction to the G500. And she's artsy, so she should be able to do some better loopty-loops.
