My old ps/2 mouse has gone fluffy so have replaced it with a usb one.
Now I find that Sonar x1c glitches from time to time - seems to stagger when redrawing mouse pointer movements.
Didn't notice it with the ps/2 mouse.
Any ideas on how to improve the usb mouse performance?
My Scarlett interface is usb2 btw with nothing else connected.

I'll bump this as I'm a little leary of USB mice/keyboards. Actually, Can you still get a PS2 mouse/keyboard?

jrmunday: post the make and model of the motherboard ..plz

If you like to minimize your interrupts then use USB and disable PS2 port in BIOS. USB is a good thing when it comes to mice and keyboards (I'm not sure it is such a great idea for sound cards, that's why I use firewire JUST for sound).

It's unlikely it's a performance issue, more like a driver bug. Upgrade your chipset drivers , or perhaps your motherboards BIOS. If you've installed mouse software with a whole load of bells and whistles consider removing it.

might be mouse software too...

I wonder what speed the USB on your motherboard is really if it has a PS/2 mouse port. That sounds very old to me. Do you think you have USB 2.0 ports but really they are USB 1.1? That definitely would cause some level of glitchiness.

Just guessing but it has definitely been a while since I saw a motherboard with a PS/2 port.

Brand new Asus here with PS2

hows the new setup timidi >? gotta be awsom

 Most Microsoft USB mice come with a PS/2 adapter; the last two I bought did, including one I bought recently for my new DAW build. I suggest the optical 3000 model. Make sure you have the visual settings in the Performance tab set to "best performance."
