Just a quick question, for anyone who uses either the WMO, the IMO 1.1, or the IME 3.0 do you notice negative acceleration when you play? What game(s) do you play with it and what sensitivity( cm/in/360 or just hi, med, low).

Reason I'm asking is these mice are pretty much known for having a lot of neg accel, but a lot of pros still use them, even at low sensitivity, so is negative accel really not that much of an issue or is everyone just not hitting it often enough for it to make a difference?

Right now I have a 17 inch CRT monitor and play @ 1024x768 with 85hz. I could go down to 800x600 to play at 100hz, but I hate the way 800 x 600 looks. I notice a big difference when I play at 1024x768 @ 75hz, and an even bigger difference at 60hz. There is only 10hz difference between 75 and 85 though, yet I notice it so much. So what I'm wondering is you guys notice the difference between 85 and 100hz(at the same resolution), or are there diminishing returns after 85hz where the difference between 85hz and anything higher won't be as dramatic as between 85hz and anything lower?

Ok I've read more than a few times that higher resolutions need a minimum DPI to achieve "pixel perfect aiming". Can someone explain to me why this is?

Right now I'm thinking the basis of this idea is that a lot of people think DPI refers to how many pixels the cursor moves onscreen for every inch of movement on the mousepad, but it actually refers to the resolution of the images taken by the optical sensor in the mouse. Ie, a mouse set to 1000dpi takes images at a higher resolution and so each image of the mousepad/whatever surface is broken down into more segments. So as a result, you have to physically move your mouse less for the sensor to detect a movement, hence the higher sensitivity you get at higher DPIs.

So is the whole pixel perfect accuracy/higher dpi/higher resolution idea, based on that first definition of DPI? Even if it is, it doesn't necessarily mean more DPI isn't needed at higher resolutions. I'm just looking for an explanation, that fits with what DPI/CPI actually means.
