This is also can be enhanced by tweaking up your mouse sample rates and whatnot. I used to do a lot of setting PS/2 mouse sample rates at 80Hz or more in late 90s that made Windows machines feel almost as nice to use as a Mac.

Isn't PS/2 interrupt based, therefore instantaneous? I think USB has 125 Hz polling rate by default which can be increased to 1000 Hz.

From Wikipedia: -

> The interface has two main signal lines, Data and Clock. ... To transmit a byte, the device simply outputs a serial frame of data (including 8 bits of data and a parity bit) on the Data line serially as it toggles the Clock line once for each bit.

Increasing the clock rate absolutely does reduce latency on a PS/2 port.
