Yesterday i read a topic on the Steam Forums about it.: "Mouse acceleration is a annoying feature found in all versions of Microsoft Windows that artificially increases the speed of your mouse cursor based on how fast you move the mouse across your mouse pad. It sounds like a great feature in theory, in fact, Microsoft even calls the setting to “Enable pointer precisionâ€; unfortunately it does the exact opposite and destroys any precision you may have had! Many gamers don’t realize that mouse acceleration comes enabled by default. Little do they know that every stroke of their mouse is different; inconsistent due to a mathematical formula calculating the speed at which they move their mouse. The game is plagued with inconsistency because moving the mouse from point A to point B is never the same. By disabling mouse acceleration, no matter how fast or slow you move the mouse, movement from point A to point B will be the same. This results in much greater accuracy, increased consistency. To disable it from Windows, open up your “Control Panel†From here open the “Mouse†panel, select the “Pointer Options†tab and un-check the “Enhance pointer precision†check-box. That is only halfway there.. Unfortunately Windows also have a smaller mouse acceleration even if you disable it. This is probably because you will not get used to mac/linux's mouse settings and will buy microsoft products so they make more $$$. You need to edit the registery to fully get rid of it. >Only continue if you have common sense. [Works with XP, Vista and Windows 7] 1. Click Start button 2. Select Run 3. Type 'regedit' in the open textbox 4. Open the tree 'HKEY_CURRENT_USER', select control panel, then select mouse 5. Right clicking, modify the SmoothMouseXCurve and SmoothMouseYCurve hexidecimal values to the following: SmoothMouseXCurve: 00,00,00,00,00,00,00,00 00,a0,00,00,00,00,00,00 00,40,01,00,00,00,00,00 00,80,02,00,00,00,00,00 00,00,05,00,00,00,00,00 SmoothMouseYCurve: 00,00,00,00,00,00,00,00 66,a6,02,00,00,00,00,00 cd,4c,05,00,00,00,00,00 a0,99,0a,00,00,00,00,00 38,33,15,00,00,00,00,00 If done correctly, you will notice you are holding a markedly more responsive mouse." from lailai So, it's correct? I can't screw something with editing the registry this way, do i? And does it help much with aiming?
As far as I know you can disable it ingame and that's all you need. Via the multiplayer tab in the options. I know I performed better with it off on CS, given the fact that it's just the distance you move that effects your cross-hair and not the speed you move your mouse with.
I did this a while ago (about 4 months ago when i saw it on the TF2 forums) and noticed no difference in my mouse movement or gameplay, the default tick box for it was already disabled, and i presume that is something the razer software does by itself; but editing the registry didn't do anything for me.
I have it on my razer mouse...acceleration in levels from 1-9...very annoying tested it but when you move your mouse a little to hard, for instance surprice behind the corner...you are everywhere with your mouse, but not on his head.... annoying, only for very calm people.
I've had it on for a while to see if you could get used to it, would be a major advantage, turning around 180 degrees in an instant for spychecks. Unfortunately... you can never get used to it. Moving your mouse an exact distance is hard enough already, having to control the speed of that movement is impossible.
It might be annyoing while playing games, but I really like it while working, since it's somehow more intuitive.
