Vampyr 0 Posted May 24, 2001 I have a USB intellimouse explorer pro. I recieve poor performance (severe stuttering, jerky movement) in Windows XP 2474. Any help would be appreciated Share this post Link to post
Brett 0 Posted May 29, 2001 Does it ever crash w/ an error related to acpi.sys?? Or check in your system log and see if there are errors in there about ACPI. I had this same problem on an abit VP6 and I simply replaced my acpi.sys in Windows\system32\drivers w/ an acpi.sys from win2k. I'm not sure how good of an idea this is but it seems to be working for me. I suggest you rename the acpi.sys file from XP rather than delete it. Share this post Link to post

CUViper 0 Posted May 30, 2001 install the Intellipoint drivers - even though it says the OS is not supported, that fixed the problem for me Share this post Link to post
luders 0 Posted May 31, 2001 I am running build 2475 and dont see the option to disable pointer acceleration. Is this possible? -Aaron P.S. I am running an Abit VP6 Dual P3 and have been having to use the MPS Multi kernel because of that mouse jerkyness. I have an optical usb intellimouse. Share this post Link to post
Vampyr 0 Posted May 31, 2001 I'm about to reinstall with the MPS Multiprocessor HAL. ACPI sux. Whoever came up with the idea should be shot and pis*ed on. Share this post Link to post
luders 0 Posted May 31, 2001 You dont have to reinstall just so you know. You can just change the driver from ACPI to MPS. One of the few switches it will let you do. Just do it from the device manager. I did it on 2475. Worked great. -Aaron Share this post Link to post
