Comment:

 yeah, so QGIS seems to be reading in the default region of the mapset, but
 then altering the resolution to that of the currently opened raster map.
 So if you turn on the Plugins -> GRASS -> Display region red box and zoom
 out, you can see that the computational region is very large compared to
 the demo map that was opened, and it will be working on a 8166 x 7350 cell
 grid. Setting the region through `Plugins -> GRASS -> Edit current region`
 then drawing a box around the current raster view isn't too great either,
 as it doesn't match the map's region exactly causing it to have to
 resample to the new grid resolution, which isn't as fast as reading at the
 native resolution.

 The solution is in the nviz startup options click on the "use region of
 this map" box to the right of the raster map dropdown list)

 should be fixed in r9082.


 thanks for noticing,
 Hamish

 ps- the trac self-logout/timeout thing is still happening! argh
