Från "Aiming By RaZiel"

USB (the flat connection):

As most ppl know, usb is supposed to be 125 hz (samplerate), and constant. That means it updates the mouse position
125 times a second. You can try the program "mouserate.exe" in the tools folder now. Move your mouse around in a
fast sircle, if it's something else then average 124-125 you are using ps2. But most of you will also notice it isn't
constant as ppl believe. Move the mouse slowly, it can even drop all the way down to 1-2 hz. Not making it constant at all.
Why is constant samplerate so important? Because of the tracking aim. Following an enemy with the crosshair over the
tarmac on mp_assault for instance. You will suffer from choppy aim if it isn't constant, and long range aim on all maps
will really not be optimal. It's reported it can be used at 500 hz in linux, really smooth movements and aiming
(only for logitech). You can't change the samplerate of usb in windows(only linux), and it's in most cases not constant.

I have read that some drivers makes it more constant, and never drops to 1-2 hz. But I have tried much myself, and never
found usb to be any bigger advantage then ps2. Most people use the usb, if they got some ideas to get it stable 125 hz,
please share. I know most of you disagree with me, and will choose usb. Some point with the dropping samplerate however;
if you keep the mouse still and then moves it. That is the moment it drops. So using lower sensitivity is actually an advantage
to keep the samplerate up, by moving the mouse a lot. High sensitivity players will suffer from samplerate drops, and aim a
lot more choppy.

PS2 (the round oldskool connection):

If you got any new mouse, there is always some ps2 adapter with it, a little thing to connect to the flat usb connection. With
this connection you can get at max 200 hz. With 75 hz more in theory then the usb, this one looks like the best choice.
However, it's not constant. Load the "mouserate.exe" from the tools folder to check it out. And the same as with usb, it can drop down
to 1-2 hz. Meaning that it isn't any bigger advantage with usb at all. Other then that you can get 125 hz, which will be synchronized
with the fps, if you got it on 125 in the game. My choice has always been ps2, because it responds faster when I need to
do some fast and crazy move to get out of a gangbang with enemies.

PS2 is set by default to 100 hz (windows XP), you can change that in
'Start->Setting s->Control Panel->System->Hardware- >Device Manager->
Mice and other pointing devices-> Double click the entry with the mousename below it'

"Advanced Settings" :
Sample rate = "200"
Input Buffer Length = "300"
Fast initialization = hooked/enabled






Vad *** ska man välja ? vilket är bäst till cs ? dom svaren skulle jag gärna behöva...
