OS X has never had a mouse tracking setting I can use with any accuracy. Leopard’s no different.
I don’t remember pre-10.2 or OS 9, but certainly with OS 10.2 and newer I’ve turned to IntelliPoint 6.22 For Mac. I use MS mice so there’s no problems with hardware/driver compatibility.
So what’s my problem? It’s the rate of acceleration the Apple driver gets all wrong. It’s like it has two speeds, slow and fast. You move the mouse very slowly — no problem. Move it quickly — no problem. But going through the mathematical line that separates these two states causes a jump in cursor speed akin to a Dodge Charger 440 launching on a 1/4-mile run.
No amount of fiddling with tracking speed in the OS X Preference Pane helps.
And — just as annoyingly — it works the same way when slowing. The MS mouse driver has a much more linear speedup, and it makes for faster mousing.

i just spend thousands of dollars on a new mac pro, and final cut pro studio 2, and additional software. I can’t get use to the tracking of my mouse. I can paint faces in photoshop using Windows Xp Operating system, but im lucky if i can draw a stick man on mac. What must i do. I’ve bought logitech mouses, worked on different surfaces, mouse pads, etc etc…does anybody want to but my editing mac pro studio from me?

I’m using USB Overdrive with a setting of 160DPI and 60% Acc. It’s decent but not like Ubuntu or XP.
