I can't afford a new mouse at the moment. I'm using a Logitech Optical mouse (ps/2) and am trying to adjust the PS/2 Report Rate to 200Hz.
The adjustment used to be made in the Device Manager but the tab no longer exists with either the MS or Logitech drivers.
I have done a clean install of SetPoint 6 (CC version 6.00.84, driver version 4.90.80). I still have no option to adjust ps/2 sample rate (it's at 100hz).
I have added the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic
I have changed the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic
I'm still at 100hz. The setting I want to change used to have a tab in the device manager where you could set mouse buffer size, ps/2 report rate, force wheel detection and I think a couple more settings. This tab does not exist in Win 7, either with MS or Logitech drivers.
I know this seems like a lot to worry about for a small setting, but I can't afford a gaming mouse at the moment and increasing the report rate give much better mouse resolution in games.
Any other ideas I can try? Logitech tech support say they can't help me with the issue.

if it is wireless it won't work. Other than that search google for a ps/2 rate switcher or something like that. Worked for me. (windows 7 64bit). Try compatibility mode maybe? Check your drivers?

I was trying change my PS/2 rate in windows 7 so I was searching for same thread that you made.
I haven't had any success so I tried research myself searching in Win XP to change PS/2 rate.
You need following settings in Windows 7 which is avi in xp.
Here are settings in Win7 to make it work.
Change settings in Controlset001 and 002 & in i8042prt or anywhere else you can find.
Basic settings are
Samplerate = c8
there you go.
I can take my Mx518 @ 197hz stable same as in WinXP.
Very few people understands
PS/2 > USB
Optical > Laser
CRT > LCD
Wired > WIreless
Good luck with it and happy gaming.

This works also with the famous IntelliMouse Optical with ps2 Adapter. I guess it works for all mice connected via ps2.
I created a .reg file that you only need to click to make the necessary changes: http://www.file-upload.net/download-3322926/ps2rat

Not sure if this is the right place but I'm out of options. And sorry in advance for a long post.
Trying to increase mouse movement in Windows 7. Cannot move the mouse cursor from one side of the screen to the other in one short movement of the mouse. The mouse movement I am trying to accomplish in Windows would be one full (or preferably less) movement of the thumb from bottom to top (left to right on the screen) of the Trackball, approx 1.5 inches in order to get from the left side to the right side of the screen. As it is I have to do it 2 times or use 2 thumb movements (not good for certain games)
I have been working on this for many weeks with no success. Searching the web and countless emails back and forth to Logitech. Tried using various Setpoint apps but only had to delete them completely out of my system. I have tried many different registry settings with no success. I am not an expert on all the components needed in order to accomplish the above but I have confirmed that the hardware is not an issue. The reason I know this is because I use multiple O/Ses and when I use Linux Fedora 13 I can go under “system settings” and make the mouse travel across the screen instantly moving it like 1/8 of an inch (which is way to fast and inaccurate to control). So that just leaves finding the right (if any) settings to make this work under Windows 7 64 bit.
New gaming pc less then 1 year old – Not really relevant to this problem but in case you need the info.
MB - Gigabyte GA-MA770T-UD3P
CPU - AMD Phenom II X4 965
RAM - Kingston HyperX 4GB DDR3 1600MHz
Video - MSI R5850 ATI Radeon HD 5850 graphics card
PS - Corsair 750 TX power supply

Relevant Hardware involved.
Monitor – Samsung SyncMaster T260, SyncMaster Magic T260(Digital) 25.5 inch screen set at max resolution of 1920x1200 @60Hz – Yes I know if I lower the resolution it will travel farther but it will look horrid and have far to little desk space to be useful.
Mouse – Old School Logitech Trackman Marble+ Model T-CL13 using the PS/2 port.

I have looked at and changed some of the following Registry settings:
The default are 1,6,10 with the settings under the Control panel> mouse>Pointer Options>Motion>set to max/far right fastest setting and Enhance pointer precision checked.
I have tried various settings like 2,4,6 1,0,0 etc. rebooting after each change and nothing increased the movement.
I then found your post here and thot maybe you might have more data to share. So I started to play with those keys with no success.
I used the MouseRate (Mouse Rate Checker 1.1b Static (c) 1998, 1999 Oliver Tscherwitschke) to verify that I had started with 100Hz and increased it to 200Hz. I only changed the above setting at first but that made my mouse move less so I tried changing the other settings but it did not get better and it was causing my boot up to take longer so I put everything back to way it was.
Other maybe possibly pertinent articles I found.
It seems to me that if we can find the right combination of settings we should be able to make the mouse move the way we want it. If however Windows (and/or Windows 7 in particular) has some restrictions then I guess we can't.
Sorry for the long post but hopefully it has enough information in it to help come up with a solution.

I am running WIndows 8.1 64 bit. Does anyone know if this fix will work there? Or is there a different fix to push the sample rate to 200 hz for WIn 8.1 x 64 bit?
I tried plugging the ps2 mouse into a ps2 to USB cord and it made a noticeable imporovement but it is still not at 200. Any ideas?
Thanks in advance.
