optical mouse resolution/does it matter?

[bleuless]

i know different brand has different res. but i heard someone said that you can adj. it in software, so it doesn't matter what you have, its the software that matters. can someone clarify this? i am interested in buying a fast mouse, and the fastest i've seen so far is the crystal mouse by Colorcase, it does 1500 dpi. this is about more than 2 times your normal mouse would do. anyone have any experience with this?

thanks alot.

You cannot adjust the resolution of the mouse. However, you can adjust the refresh rate of the mouse port. A PS/2 port defaults to 60Hz but can be set as high as 200Hz. USB is 125Hz (I think) but it cannot be changed as far as I know. In this case, 1Hz is one check of the mouse per second.

Sure it matters: they can charge you more for bigger numbers!

what does the refresh rate do? is it sorta like resolution? the higher the refresh rate, the faster you mouse can be?

The higher the refresh rate, the more accurate your mouse is. I wouldn't worry too much about it.

Think of refresh rate as the number of "samples per second". At a 60Hz refresh rate, the computer querries the mouse for position data 60 times every second. At 125Hz, it querries 125 times per second. And at 200Hz, it querries the mouse for position data 200 times each second. Naturally, higher is better. However I personally cannot tell a difference between 60Hz and 200Hz, and unless you are doing some very high end stuff where you need maximum accuracy from the mouse I cannot imagine that you'd notice a difference either.

The refresh rate, and possibly the resolution can make a difference in 3d gaming. In first person shooters where you aim and pan using the mouse you will notice a difference. You can aim much quicker, and be more accurate with faster refresh rates. This is primarily why I occupy a USB port for my mouse. The concept works much like a lever. At the point that you're moving, it may be a small distance, but at the end of the lever, or your field of view the difference is more draumatic. People mistake choppiness sometimes with slow frame rate which isn't always the case. For working with graphics, you may want to consider more accuracy as well depending on your needs. I've found that cheap mice use a ball that has a seam on it. The seam will affect your ability to draw or aim smoothly as well.
