{Hmmm} USB SchmUSB

Having the USB devices plugged in doesn't seem to matter.

The drivers are causing the problem, and these are enabled despite the absence of the external devices.

People are having positive results when they disable all "HID-compliant" devices in the Computer Management console. I've done it, and it doesn't affect my current ability to use either the native laptop keyboard or the external keyboard + mouse.

This absolutely worked for me. No more chugging, even while windowed.

Here's the thread on alla.

I'm on a MacBook Pro
Intel Core Duo 2.33
the adapter through boot camp is currently: ATI Mobility Radeon X1600

Now I'm working on the ghetto anti-aliasing problem. I'm testing slight increases to values in the Overlay resolution to account for the additional pixels from the window "box." If I can compensate accurately, I think the windowed can be made to look fine. Will post details here as soon as I get them.

Addendum (12/5/07): I've discovered that, for whatever reason, 1360 x 768, seems to be the maximum resolution supported by the native windowed mode. When the overlay resolution is set to this, and the gamma is adjusted appropriately, everything works fine. It's disappointing that the windowed mode seems to be subject to the same problems with Vertical Sync as the unofficial windower (i.e. Vertical Sync doesn't really work here). But at least it doesn't look like butt anymore.
